摘要
良庄井田目前已进入深度开采,以断层为通道的奥灰岩溶水对底板突水问题的影响越来越大。针对该井田11煤层开采底板断层突水问题,在概述良庄井田构造发育特征的基础上,以分形理论为指导,提出采用断层分维值及断层强度指数对良庄井田煤层底板断层进行定量化描述,并融合突水系数和涌水量对井田的突水危险性进行了分区。利用灰度分析Python编程确定断层分维值、强度指数和突水系数的权重,采用Surfer中的插值法将3个参数融合分析突水危险性,根据突水危险性将该区域划分为突水危险区和开采安全区。
In view of the problem of water inrush from floor in mining of coal seam 11 in Liangzhuang mine field,on the basis of summarizing the characteristics of structure development in Liangzhuang mine field and guided by fractal theory,fault fractal dimension value and fault strength index are used to quantitatively describe the fault of coal seam floor in Liangzhuang mine field,and the risk of water inrush is divided by water inrush coefficient and water inrush volume.The grey level analysis python program is used to determine the weight of fault fractal dimension,intensity index and water inrush coefficient,and the interpolation method of Surfer is used to fuse the three parameters to analyze the risk of water inrush,and according to the risk of water inrush the area is divided into the risk area of water inrush and the safe area of mining.
