融合突水系数和断裂构造分维值的工作面底板突水危险性评价

摘要

针对北皂煤矿H2108工作面开采受底板中砂岩突水威胁的现状,在综合分析工作面水文地质特征和底板突水危险性影响因素的基础上,为解决突水系数法评价煤层底板突水危险性的局限性,提出运用信息融合的方法将突水系数与断裂构造分维值相融合,对工作面开采突水的可能性进行了综合评价,并对煤层底板突水的危险区域进行分区与预测,得出了北皂煤矿H2108工作面总体能实现安全开采的结论,给出了工作面安全开采底板突水防治措施.%In allusion to the status quo of the Beizao coalmine working face H2108 mining threatened by floor sandstone aquifer water bursting,on the basis of working face hydrogeological features and floor water bursting hazard impacting factor integrated analysis,to avoid limitations from water bursting coefficient method coal floor water bursting hazard assessment,put forward the data fusion of water bursting coefficient and faulted structure fractal dimension value.Then comprehensively assessed working face mining water bursting possibility and carried out coal floor water bursting hazard area partitioning and prediction.The conclusion is that the working face safe mining can be realized,and working face floor water bursting control measures worked out.
