张沟矿建筑群下“三软”煤层条带开采的可行性研究
首发时间:2012-11-16
摘要:张沟矿煤层及煤层顶底板岩性较软,属于典型的"三软"煤层,地表存在七栋居民楼,位于16采区上方,如果为其留设保护煤柱则造成大量煤炭资源的浪费,本文结合建筑物群的具体情况,设计了建筑物群的保护煤柱;确定了条带开采的参数;为确保建筑物群的安全,采用了概率积分法对开采引起的地表变形进行了预计,结果显示在张沟矿建筑物群下进行条带开采可以达到保护建筑物的目的,同时具有良好的社会和经济效益。

Feasibility Study on Strip Mining under Group of Buildings in “Three-Soft” Coal Seam in Zhanggou coal mine
Abstract:The coal seam, roof and floor are soft in Zhanggou coal mine. There are seven buildings on the ground of No. 16 mining area. If the protective coal pillar is designed for the buildings, it will waste a lot of coal resources, In this paper, protective coal pillar was designed combining with the specific conditions of buildings in Zhanggou coal mine. The mining and retaining width was finally determined. To ensure the safety of the buildings, surface deformation caused by mining was predicted by probability integral method. The results show that the surface buildings in Zhanggou coal mine will be well protected by using strip pillar mining.
Keywords: Mining engineering Coal mining under group of buildings “Three Soft” coal seam trip mining Prediction of surface deformation
