官地煤矿02^(#)煤层蹬空开采可行性论证

Feasibility Demonstration of Overhead Mining in 02^(#)Coal Seam of Guandi Coal Mine

通过比值判别法等几种常用的方法对官地煤矿02^(#)煤层蹬空开采可行性进行了论证。通过几种判别方法,并结合02^(#)煤层与2^(#)煤层之间的层间距、2^(#)煤层顶板岩性情况,得出了02^(#)煤层无法进行蹬空开采的结论,可为矿井生产衔接安排、采区规划布局提供一定的技术依据。

Through several common methods such as ratio discriminant method,this paper demonstrated the feasibility of over-head mining in 02^(#)coal seam of Guandi Coal Mine.By several discriminant methods,combined with the interval between 02^(#)coal seam and 2^(#)coal seam,and the roof lithology of 2^(#)coal seam,it was concluded that 02^(#)coal seam can not be mined,which can provide a certain technical basis for the connection arrangement of mine production and the planning and layout of the mining area.
