Underground reservoir site selection method beneficial to mine water quality purification
The underground reservoir site selection method beneficial to mine water quality purification comprises the steps that rock stratum parameters in a caving zone in a goaf are determined, lithologic compositions in the goaf and the proportion of the lithologic compositions are determined according to the rock stratum parameters, the lithologic compositions comprise residual coal, sandstone type rock and mudstone type rock, and it is determined that the proportion of the mudstone type rock is smaller than a first set value; the drilling area with the ratio of the sandstone rock to the residual coal or the sum of the ratios of the sandstone rock to the residual coal is larger than a second set value serves as a candidate area, the area ratio of the candidate area to the goaf is judged, and if the area ratio is larger than a ratio threshold value, the candidate area is suitable for constructing the underground reservoir. According to the method, the water purification advantage of coal and sandstone rocks is fully utilized, the goaf with the large proportion of lithologic rocks existing in the caving zone is selected as the construction address of the underground reservoir, the water quality of the water body out of the reservoir and the water body reuse efficiency are effectively improved, and the method is simple in step and low in cost. And the operation cost of the underground reservoir construction process is effectively reduced.
本发明提供的利于矿井水水质净化的地下水库选址方法，包括：确定采空区中的垮落带内的岩层参数，根据岩层参数确定采空区中岩性组成及其占比，岩性组成包括遗煤、砂岩类岩石和泥岩类岩石，确定泥岩类岩石占比小于第一设定值，或者砂岩类岩石与遗煤的占比之和大于第二设定值的钻孔区域，以钻孔区域向外延伸设定距离作为候选区域，判断候选区域与采空区的区域占比，若区域占比大于占比阈值则候选区域适于建造地下水库。本发明充分利用煤、砂岩类岩石对水体的净化优势，选择垮落带中赋存有这类岩性岩石占比较大的采空区作为地下水库的建设地址，有效提高水库出库水体水质和水体复用的效率，且本发明步骤简单，有效降低了地下水库建造过程的运行成本。
