多煤层开采过程中,由于重复采动,岩层及地表移动过程具有加剧情况,移动速度和变形值加大,对地面建筑物有较大的破坏。这种老区活化影响的规律性有待研究,尤其开采残留煤柱时,老区活化影响范围还发生在开采边界处,更具有其特殊性。蛟河煤矿奶子山填建筑物下,采用了减小地表移动和变形的“变采留比倾斜冒落条带法”,开采了原留设的保护煤柱, In the process of multiple coal seam mining, due to repeated mining, the process of rock formation and surface movement aggravate, and the moving speed and deformation value increase, which causes great damage to the ground buildings. The regularity of the influence of this old area activation needs to be studied. In particular, when the residual coal pillar is exploited, the influence of the activation of the old area occurs at the mining boundary and has its own particularity. Under the construction of the Dazhushan fill-in buildings in Jiaohe Mine, a “change-over-stay-over-dip roadway striping method” was adopted to reduce the movement and deformation of the ground surface and the original pillar of coal pillar was mined.
