辽宁省梨树沟煤矿区地质环境恢复治理浅析

梨树沟煤矿历经多个开采阶段，形成大面积的采空区及大量的废石堆，并引发地面塌陷、地面沉降及地裂缝等多种地质灾害，耕地、植被、水环境及大气环境等生态环境遭到严重破坏.采用物探、钻探等多重技术圈定采空区，实地调查桥梁、道路破损程度，针对桥梁、道路、采空区、废石堆等采取钻孔回填、灌注加固、搬运平整等不同技术手段进行处理.分别就坍陷坑、采空区、道路、废石堆复垦及水环境保护和花园式绿化提出不同的施工方案及技术要求，对该矿区地质环境恢复治理提出行之有效的建议.

PRELIMINARY ANALYSIS ON THE GEOLOGICAL ENVIRONMENT RECOVERY IN LISHUGOU COAL FIELD, LIAONING PROVINCE

After a long period of mining,the Lishugou coal mine is left with large mined-out areas and numbers of waste heaps,causing ground collapse,land subsidence,geofractures and other geological disasters.The cultivated land,vegetation,water and air environment have been severely damaged.To locate the mined-out areas,geophysical exploration and drilling techniques are adopted.The damage degree of bridges and roads are investigated on the spots.The technical methods of drilling and backfilling,perfusion,moving and leveling are used.Different construction plans and technical requirements are made for the recovery of geological environment of the coal field.
