龙宫煤矿井田开拓方式的探讨

通过对龙宫煤矿井田开拓方式的探讨,得出结论:本井田1、2号煤层赋存稳定,煤层倾角在3°～6°之间,对井田开拓无影响,但对井田开采有一定影响;本井田1、2号煤层均存在采空区,主要在井田北部工业场地附近存在采空区,对井田开拓开采有影响;全井田1、2号煤层以+747m一个水平开采,将井田划分为2个采区开采,矿井先期开采位于开拓巷道南侧附近的一采区。

Probe into the Methods for Minefield Development in Longgong Coal Mine

This paper draws the conclusion from the exploration of the methods for minefield development in Longgong Coal Mine that occurrence of No.1 coal seam and No.2 coal seam of this minefield is steady, the coal seam inclination is between 3°and 6°, having no influence on minefield development, but having certain influence on the mining of minefield; and there are goals in No.1 coal seam and No.2 coal seam, mainly near the industrial site in the northern part of the minefield, having certain influence on the mining of the minefield; and the mining of No. 1 coal seam and No.2 coal seam of the whole minefield is conducted on a same level, and the minefield is divided into two mining areas, the prior mining is developed in the fist mining area near the south side of the roadway.
