煤系顶板砂岩含水层富水性分区研究
|
摘要
为探讨禹州煤田西南部云煤二矿软煤、软底和硬顶且开采煤层厚度变化很大的两软一硬不稳定煤层顶板富水性,以某预开采的工作面研究区为背景,在采掘资料和钻孔数据统计分析基础上,建立了典型钻孔柱状对比图,并进行了岩组类型划分和导水裂隙带高度的计算。在此基础上,采用主采煤层顶板岩性结构指数法对研究区顶板富水性进行了探究,获得了研究区各个钻孔位置裂隙带以内的顶板岩性结构指数量化值,通过内插进行了等值线变化特征分析。然后采用标准化方法对岩性结构指数进行富水性分区,划分出富水性相对弱、中等和强3个区域,与实际情况进行了对比。研究结果对研究区预采掘顶板水害防治及顶板支护具有较重要的参考价值。
In order to explore the water-rich roof of two soft and one hard unstable seams in Yungaishan No.2 Coal Mine,southwestern Yuzhou Coalfield,where the thickness of mining seam varies greatly,based on the statistical analysis of mining data and borehole data,a typical borehole column contrast map was established,and the rock group types were classified and the height of water-conducting fracture zone was calculated.On this basis,the main coal seam roof lithologic structure index method was used to explore the roof water rich property in study area,and the quantitative value of roof lithologic structure index within the fracture zone of each borehole location in study area was obtained,and the contour change characteristics were analyzed by interpolation.Then,water-rich zoning of lithologic structure index was carried out by standardization method,and three regions with relatively weak,medium and strong water-rich were divided,which were compared with the actual situation.The research results have important reference value for prevention and control of water hazard and roof support of pre-mining roof in study area.
