CLARK, ESQ ., Vice-Pres i dent & Gener a.1 ?.lanagcr , Union Pac ific Coal Company , Omaha , Nebraska . Dear Sir: I n t r o d u c t o r y: In accordanc e with your instruct ions, I made an examina tion of No. 3 Mi ne at Hanna , Wyoming , and, as di r ected in your letter of February 6th, I added to my general examination, a careful inspection o:f the coal seam throughout - 1 - �the u nd erground workings to find localities where coal 0£ an inferior quality was being mined, of which I shall v,rite you later on in this report. The Coal Seam Forms A Semi-Synclinal Bas in, outcropp ing to the north, the east and west, and cut off by a downthrow fault adjoining No. 1 Mine on the south. See map attache d at end of the report. In all my mining experience , I have never seen (in part ) a mor ~ characteristically formed coal basin confined to such a limit ·.d area. The axis of the basin passes thr ough approximately in proximity to room 31 on No. 1 Entry, No . 19 room on 3rd Entry , and No. 10 room on the 5th ]Jntry. See map at end of this r eport . The Mine Con iata Of A Slope Open ing , entering from the western "rim" of the synclinal, and is driven in a southeasterly direction towards the center of the basin, cros ses the "t r ough " and cont i nues on i te course to the raise to wards .,.,...,d at the the out crop on the eas t ern "rim" of the synclinal, ..... A time of my visit, i t l a cked only a few feet of being through to the surf ace, thus, from "rim to rim" of the baa in, the line of the slope forms the s hape of a bow. - 2 - �Entri Gs No s . 1, 3 and 5 a r e turned from the northerly side of tho slope on the "st rik e" of the c oal seam , and to maint ain a l evel course for mule haul age , they ne ces sarily extend in a d irection formi ng a s emi-c ircl e ar ound t he "bowl" of t he b as in, back towards the slope. Sec attached map o The Th ickness Of The Coal Seam, i s about 18 to 20 f ee t, un if ormly throughout the min e , and i s d i v i ded by a "part i ng 11 of slate about . six· feet from the top. At a point about six to seven fe et under the "par t ing", above mentioned , there i s a stratum of carbonac eous shale f r om two to four inches in thi ckness, and th i s , wit h six feet of c oal , is left on the fl oor under the tracks , in entries. The Q~a1ity Of The Coal , is a lignite of a fairly go od gr ade , aa the foll owing analys i s will show: .Mo isture,------------- 9 .47% Volat ile .Mat ter ,------ 42.51 F ixe d Carb on ,---- ----- 44.14 •Ah 5 ' --~-~~-~---- ~~ ---- 3.88 100.00% Specific gravity, 1.288.

A Good Deal Of "Crop" Coal ~as Being Mined , at the time of' my vioi t and vlas p erc ept ibly 0 ea rthy" and quite inferior in qu ality . In No . 1 Entry , n ear tho f ac e , the coal v ery soft and soggy , liko "peat'' , and the same 'was more - or - l e s s true throughout 20 r ooms back from the face of 'Wlo entry . See map and no te thei r cl ose proximity to the line of out crop . A fall of r oof had taken place at the face of the entry, .,hich sho.~cd a coverin ··· of surfac e c lay over the coal seaI!l of only 1 2 to l n f eet in thi c kness , and in a number of the rooms , th~ cover is about the same thickness . I have no do ubt but mu ch of the c ompl a ints made to you a bout "poor~ c oal cam~ fr om this s ourc e . A Gob Fire F rom Spont rneous Combustion , occurred in No . 3 room of No . 1 Entry abo ut nine months ago, resulting from a cave-in of the roof and froD t h e fact, no doubt, that a mixtur e of clay, debris and f ine coal heated under this fall. The f'irc was su cc essfully 1alled off with stone stop - ping s for a distance of six rooms, and at the time of my visit, the t empe rature in their vici nity was found to be normal. "But, a.s the fire will get air through the c aved stra t a to support combustion , it is doubtf ul il' it has 'been entirely extineuished, and yet, carbcni c ac i d eas C. o.2 may have formed to • such an ex t en tao.... to arrest th ! pr ogreso of combustion , - 4 - �though we have no means of determining this . In future , i.'·h en sto pp ings are put in, to \fall off fires, I would re - commend that u. pipe ~,ith a vc:;.].ve be built into the wall of the stopping so that the character of gases formed , if any , could be determined from time to time . Y.a.r sh Gas ("Fire Do.mp" ) c .H4 ., ma never oeen de tected in this mine , from the f3.ct , no doubt, that the workings have been approximately near the outcroppin5 of the coal seam and. the covering of strata ( over the coal) bc'ing com- paratively shallow, and no ~. tha,t the strata is more-or-less broken , it is not likely that expl o~ivc gas will ever b e met ~ith in thi s mine: I iound , hov1ever , that the precaution of having gas ,,at chmen to examine the underground .. orkings .vas being observed 1 and a daily record bock kept and examinations ins cribed therein ~,i th the same regulari tv as if gas were present and expected. Rut in making a search through this book , there was not an instance in uhich the presence of gas had been recorded. While I think it doubtfu l that gas \7ill be met id th there, yet I was pleased, not a lit t l e , to sec that a car eful daily search with safety l aJ!lPS was beint; made b ef ore the d the wor kmen ea.ere t ir . ;orking places . • ""P..ith:i:'ul c ontinuance of such inspections.

The System Of Mining , is that of ftblasting from the s~lid", no mining or shearing is done to lessen the binding r esistance of the coal seam lying in pl a ce, but is ruthlessly blasted from its solidity o_f bed.

APRIL, 1911. To: D: O. CLARK, ESQ., Vice-President & General Manager, Union Pacific Coal Company, Oma.ha, Nebraska. Dear Sir: I n t r o d }1__£_ t o r Y.: In complian~e with your instructions, I made an examination of Nos. 1 and 2 Mines at Cumberland, Wyoming, and herev-vi th present to you, my report on the same. The Mines Consist Of Slope Openings, driven on the true di p of the coal seam, thus the entries • run on the - l - AL MINEO. �\ "strike", at right angles to the slopes, making good, "square" work in the mines and a pleasing appearance on the maps. See nw,ps attached at end of this report. The DiE...Qf_1P~ Co~l Seam, is in a westerly course, and the inclination is (from the horizontal) about 22-1/2 degrees. The Thiclmese Of The Co_al Seam, varies, according to location, from about 8 feet to 19 feet, with a seam of clay from 10 inches to 10 feet in thickness about five feet from the bottom of the coal. 'Wherever this intervening clay is not over t wo feet in thickness, it is removed and the bottom coal is taken up. The Quality Q! The Coal, we may accept as a nonco~ing bituminous, is good steam fuel a.nd for general heating purposes, but is not as favorably received for domestic use as Rock Springs coal . vs es: .Anal • r-----No. 1.

A fe v1 ye ar s af,O, when the vertical _ covering of the strata overlying the co e,l searn had reached a thickness of 1,500 feet or more, it was found that the pillars left, in advancing the Work, were insuf f icient to withstand the pressure brought to bear upon them and resulted in there being s uch a severe "bl t 1 ep the workcrush tha t i t beccl.2J1e prac'tically impossi e O ce '-' ing ~s p open ; eJ.'lct ~ in =as-m.uch as oar coal e;en e ral 1y , and that - 3 - the south entries hacl run into t,.ne north entries and the slope �\ I tad rea ched the rock fault (an unknown quantity), also that the p illars ,;er e c r ushi ng and t h e presence of marsh gas C .E . 4 v1as ruo1·e-o r -l e s s t r oubl esome, it was decided to abandon and seal off the workings under No . 3 Entries and take out wh a t~ ever co a l that could be gotten fr om Nos. 1, 2 and 3 North Entr i es, whi ch, under existing c onditions, was really the only course to pursu e . The Daily Produc tion_ Of The Mine, at this time, is about 800 to ns of run-cf-mine coal. The 1st North Ent r.z, at the present time, con- tributes about 75f; of th e above output, for the following good reason explai ned. by Supt. JJcCarty, that he wished to extract all t h e co a l f rom the pillars from 70 to 80 rooms and have the space cav ed in to take off the ·lflr night and pressure of the s uperi ncumbent strata before attac king the pillars at the face of No. Entry No. 2. I estimate that gof, of the pillar coal no~ in No. 1 No. Entry, nort h of' t h e boundary line ( Quea ley le,nd) can probably be remo v ed . From Room 40 to Room 29, a "squeeze" of t h e overlying strata upon the pillar s has been active f or sometime , a nd it Will b ea very diffi cult matter t 0 extract mor e tha n about l5fv" of t he co a,l remaining in • th e se pillars. - 4. - �In advancing the first workings in these entries, it is n11·ned ou~; ~ 35r, d evi dent that 65% of the coal mas " however, would ha ire been much better mining. In 2nd North E~try 9 between the fault and boundary line (in Quealey land), I estimate that 90% of coal in pillars will be extracted.

The General Equipment of The Mine, is very good in all 1·t s branches, and it is a source of regret, indeed, th at an additio nal coal area cannot be found in the vicinity of Cumberland. Not having personally examined the field, I can have no decided opinion to offer in this connection. Th e Op era tion Of The Mine As To Safe ty, of employees, is fairl~r _ go od . I."'ining pillar coal is a ccompanied ~vi th a greater degree of danger from falls of coal and roof than fr om rooms , but, seemingly, very few accidents from lllin lng • this sour c e have occurred in working these pilla rs. ·- 7 - �----- - : ,- -_~ ,,.....,..~======-~- It wi ll b e understood that in min~ng out pillars, but a mi n i mum amount of bl as ti ng is r equired, and as there is always a "free-end" to shoo t t o , the danger in this risk is reduced to a mi n i mum. I n Conclusi on, seeing that the end of No. 1 Mi n e i s draTiing t o a close ( 18 months at mo s t) and that nec e ssary safe -guards are in evidence f or the comfort and safety of t h e workmen, it -·rnul d be superf l u ous to continue this report further.

It will be observed that f rom t he 10t h North and 10t h South Entries down , large pillar s ar e l ef t on each s i de of the slope bet ween entries. This prec aution was an abs olute necessity, for the purpose of arr esti ng f ur t her devel opment of pressure from a general "creep" or squeeze of the overlying strata upon insufficient pillar s, wh ich was brought about by a seemingly common, but inexcusabl e mi stake, in · rn rking out §:.!! altogether too large ]ercentage of ----the -----~ coal ..seam -in advanci~ -th~ w~r kings of the --=- ----== -,.;;.~ ~ -.:.-..re...... - "mine.

Dear Sir: • P r e f a t o r y: Acting upon instructions received f rom you, I made of the work done at Reliance, and I herewith an e:x:a:m.1 na t ion • Preeent th i s br ief report on what I saw there. The operations being followed, at this time, are in a Pr ogre ssiv e state of development • but with sufficient - l - �!glOWll di s c l osures in the coal me asure s t o place the venture safely b eyond experiment ( as the prospe c t work now perf ormed has proven b eyond any r easonabl e doub t that the co al bearing rocks a re underla i d wi th v ari ous seams of coal of such thi ckness and of s uch qual i ty aa t o make the future success of t he Re l iance c ollie ri es now appar ent). The Locat i on Of Reliance , is about six mil es in a nort herly direct i on from Rock Springs , in Township 20 No rth , Range 104 :'"est. No . 1 Mine is opened in Secti on 31 . The Coal Formation, extends from Rock Springs, and the outcrop of the s eams may be traced from the re on to Re liance.

I wo uld r e c om.nend. that only 40,% of the co al seam be mined in advrnc i ng th e v10 rk ing::3. But , bet ter s till, I would strongly advis e t ha t entri es , whe r ever pos sible, be driven to the boundary and work b ack by the r et r eating system from there. See plan herewith attache d at the end of this report. I did n ot make any exami nat ion al ong lines geologically , in the corr Alat i on of the se8Jlls, but I understand that th8 coal bed horizons :from "B" to "F " are embraced within th e measures in por tions of the di strict, and no dou~t a vast tonnage of av-ailable coal wi ll be f ound at Reliance arrl. its "i'icinity.
