摘要
为查明七五井田范围内村庄房裂现象与井下采煤的关系 ,应用开采沉陷计算法确定开采影响范围。在与邻近矿区进行地质条件、开采方法综合比较、分析的基础上 ,确定了合理的计算参数 ;并将所求得的开采影响边界与其它方法所确定的开采影响边界相互校核 ,得到了最终开采影响边界。结果证明 ,房裂与井下开采无关。其主要原因是区域地质构造活动。
The calculation method of mining subsidence is used to determine the mining influence scope to investigate the relationship between room crevice phenomenon and subsurface mining in Qiwu mining district.Based on comprehensive comparison and analysis of geologic conditions and mining method,reasonable calculation parameters are determined,the final boundary of mining influence is detemined with adjustment for calculated boundary and the boundary determined with other method.The result confirmed that there is no relationship between room crevice and subsurface mining.The analysis indicated that the room crevice is caused by regional structure movement,engineering geology and building quality.
