徐州矿区张集煤矿属厚冲积层、高潜水位平原矿区 ,其西三、西六采区上方地面有多个村庄建筑群。应用岩层控制的关键层理论 ,提出了因地制宜布置极不充分开采工作面控制地面沉陷的方法。地表沉陷预测和初步的地表沉陷实测结果证实了该开采方案是可靠的 ,并可保证开采区上方地面建筑物安全
Zhangji coal mine in Xuzhou mining area is a thick alluvium, high subduction level plain mining area, the West Third, West six mining area above the ground with multiple village buildings. Based on the key layer theory of rock control, a method to control ground subsidence due to the extremely inadequate mining face is proposed. Surface Subsidence Prediction and Preliminary Surface Subsidence Test results confirm that the mining scheme is reliable and can ensure the safety of ground buildings above the mining area
