摘要
调查了榆神矿区大砭窑煤矿地面塌陷及地裂缝现状,以煤矿开采的历史、区域地质概况及煤层开采情况为背景论述并总结了采空区分布范围、地面塌陷和地裂缝分布特征。研究了大砭窑煤矿以房柱式开采和机械综采两种不同开采方式引发地面塌陷和地裂缝的展布规律,并将矿区划分为高、中两个易发区。根据地质灾害易发程度和区内地质灾害点险情等级,将矿区划分为地质灾害高危险区和低危险区。
The surface collapse and ground fractures in Dabianyao Coal Mine in Yulin-Shen- mu mining area were investigated. Taking the mining history, regional geology and coal mining situation of Dabianyao Coal Mine as the research background, the distribution range of gobs and the distribution features of surface collapse and ground fractures were discussed and summarized. The distribution laws of surface collapse and ground fractures in Dabianyao Coal Mine were stud- ied, and the surface collapse and ground fractures were caused by two different mining way~, room and pillar mining and fully mechanized mining, and the mining area was divided into the high easy-happening area and medium easy-happening area. According to the easy-happening de- gree and dangers grade of geological disasters, the mining area was divided into high danger zone and low danger zone.
