村庄下压煤短壁间隔充填开采技术研究与应用

为了解决村庄压煤遏制矿井可持续发展的问题，以刘东煤矿10#煤层压煤开采为研究背景，提出四种开采方案，运用经济学原理确定了采用短壁间隔充填开采方式回采刘东煤矿510采区村庄压煤区域。然后，结合关键层理论及结构力学特征确定了条带充填宽度和充填体强度，采用FLAC3D数值模拟软件确定了充填开采回采工艺。最后，应用室内物理模拟方法验证确定了充填开采工艺参数及回采工艺的准确性。通过上述分析结果可知应用短壁间隔充填开采技术可成功回采村庄压煤采区，对相似条件下的村庄压煤开采具有重要的参考意义。

Study and Application of Mining Parameters Selection of Short-wall Interval Filling under Villages

As one of the "three under" coal pressure problems, village coal pressure has long puzzled the sustainable development of the mine. How to extract the pressure coal resources by reasonable mining method is an important subject of "three under" mining work in our country at present. In this paper, by comparing and analyzing the economic benefits of various mining schemes to solve the problem of village coal pressure, the short-wall interval filling mining method is adopted to extract the village coal pressure mining area of Liudong Coal Mine. Combined with theoretical analysis, physical simulation and FLAC3D numerical simulation calculation method, the strip filling mining technology parameters and mining technology are determined. Finally, the short-wall interval filling mining technology has been successfully applied to the mining area of village coal pressure, which has a reference significance for the mining scheme of village coal pressure and the way of village relocation under similar conditions
