摘要
为解决吉郎德煤矿B5、B8下煤层缓采制约采坑降深造成的生产接续困难,对开采顺序进行优化,提出对西帮进行纵采转横采扇形转向的开采方式,以解决矿坑正常生产接续等问题。实践证明:将西端帮分区进行纵采转横采,采用局部以18°为转角的扇形转向方案,能够合理的处理好生产组织关系,保证生产接续平稳。
In order to solve the problem of slow mining in B5 and B8 lower coal seam of Jilangde Coal Mine,which restricts the depth of mining pit and brings difficulties to production connection,the article optimizes mining sequence,and puts forward the mining method of vertical mining to horizontal mining with fan-shaped corner to solve the problems of normal production connection.Through the analysis and research,we conclude that the west end slope will be divided into vertical mining to horizontal mining,and partial mining with 18°angle.The implementation of the scheme can reasonably handle the production organization relationship and ensure the smooth production connection.
