霄云煤矿12_下煤井下补勘钻孔施工可行性研究

The Feasibility Research on Underground Drilling in 12 below Coal Seam of Xiaoyun Coal Mine

12下煤是霄云煤矿经济可采煤层之一,由于该煤层与3煤相距约100m,煤层埋藏较深,多数钻孔未能穿过该煤层,造成地质资料缺乏。本文通过对井下补充勘探钻孔施工的可行性和经济性进行论证,证明在井下进行补勘施工是是非常必要的,也是经济可行的。

The 12below coal seam is one of the economic available coal seam in Xiaoyun Coal Mine,because of this coal seam is 100m away from 3rd coal seam and deeply buried,and could not get through this seam with many times drilling,which cause the poor of geological data. This thesis discuss about the economy and feasibility of complementary underground drilling,which prove the complementary underground drilling is necessary and economic reasonable.
