Richard: Your letter of date October 6, r equesting information concernine limit of depth of cover for succes sful ex.traction of coal s eam by room and pillar method. tluy I correct your stater.1ent that the 1·:inton No. 1 L1ine has not been in operation since Auf;Ust~ 1948. The ·.-.1inton No. 1 !ine v1as in oparation at the time of your visit in Hay and i s continuin.., operation at this time. It is unfortunate that you did not av.nil yourself of the opportunity to observe conditions ·present in the 1:Jinton tJo. 1 !jine. r:a are successfully executing room and pillar method of extraction in ;·'J inton No. 1 Hine under approximately 1800 fe et of cover. The sinking of the slope at Winton No. 1 nas stopped due to encountering unmerchuntable coal ( excessive impurities) rather than depth of cover. There are so many variables to consider in determining the maximwn amount of overburden for successfully extracting coal by room and pillar ·method that ne defer making any comment on your problem or that of others without detailed information., followed by a precise end c o.reful engineering analysis of same. Further, it has been my personal experience that an engineering analysis does not alv1ays indicate or solve the mining problem. In short, it is necessary to apply good engineering practice and thereafter a 11 cut and t.ried 11 method to determine exactl,7 v1hat can be accomplished under prevailing conditions. In the Rock Springs field it has been · pretty nell determined that with overlying shales and sandstones a r.:i.a.ximurn cover or over-burden of 2000 feet limits the full and economic extraction of the coal seam. \'le are sorry to decline your request for geologic sections, together v1ith tensile streneth of overlying strata in coal seams and resultant pressures as same would entail a very expensive procedure on our part.

You have received quite a number of visitors from France and there is nO\Y quite a discussion taldng place in France between • those Vlho favor the Roan and Pillar system and those who favor the LoDg\Vall system. Each camp has been hauling figures at the other about the percent~ of recovery o£ coal sea.ms taking place in Rockspring. They have asked me to get in touch with you in order to find out the ax:act data. Sane claim that you recover as much as 90% of the coal seams, others claim it is only 30% •. During my visit there about a year ago together with Messrs. Franceschini and Or~ire, I visited the mine Winton No. I and came back with the figure of about ~5 to 90% recovery ..
