为了确保矿井接续及生产,确保地表建筑物安全,沙坪矿以岩层控制的关键层理论为指导,提出井下采空区局部条带充填减沉技术.该技术利用充填材料充填构建平行于工作面煤壁方向的矩形条带,凝固后充填体控制上覆岩层活动,保证地面建筑物安全.“,”In order to ensure mine succeeded and production and ensure that the surface building safety, key strata theory in ground control as the instruction, underground goaf local banding pack reducing heavy technology was proposed. Filling material filling construct paralleled to the direction of working face coal wall rectangular strip, after solidification filling body controled on the overlaying strata movement and ensured the surface target building safe.
