摘要
斜沟煤矿主要可采煤层之一的13号煤层煤层厚度5.95～16.68 m,平均13.88 m,煤层底板标高260～940 m,采用放顶煤开采;奥陶系岩溶含水层为斜沟井田内主要含水层之一,水位标高850～854m。要对13号煤层充水条件及其带压开采进行评价并提出防治水措施。
No.13 seam is one of main to 16.68 m （13.88m on average） and floor karst aquifer is one of main aquifers, with filling condition and mining above aquifer, minable seams in Xiegou mine, with thickness ranging from 5.95 m level from 260 m to 940 m. Top coal caving is adopted. Ordovician water level ranging from 850 m to 854 m. The study evaluates water and then proposes water control measures.
