摘要
针对条带煤柱炮采工艺效率低、人员多的实际情况,组织开展了机械化充填开采技术研究,形成了平行条带布置工作面机采充填技术,对地表移动变形进行了采前预估,地表在Ⅰ级损坏范围内,可以实现安全高效开采。
Aiming at the actual situation of low efficiency and large number of personnel in strip pillar blasting mining technology,the mechanized backfilling mining technology was organized and developed,and the parallel strip layout face mechanized backfilling technology was formed.The surface movement and deformation were predicted before mining.The surface could be safely and efficiently exploited within the damage range of grade I.
