摘要
结合双山井田综采放顶煤条件下导水裂隙带发育高度值预测,依据唐山分院公式(软弱岩层),计算全井田导水裂隙带发育高度最大值和柳巷河河道沿线以下煤层采用只割不放的保护性开采方式时最大值。将理论计算和周边已成井田现状调研相结合进行分析,结果表明,双山井田开采后导水裂隙带发育导通地表含水层,造成地表水通过裂隙带涌入井下的可能性较小。
Combined with the f ull-mechanized caving mine condition, the article forecasts the development height of the fractured zone of conducting water. According to the formula of Tangshan branch（the weak rock）, it calculates the maximum height of the development of the fractured zone conducting water in the whole well and the mining maximum value of the coal layer with the protection method of only cutting without going along Liuxiang river side. It is based on the coal seams below the Liuhehe river are calculated by using the prediction of the development height of the hydraulic fractured zone under the conditions of fully mechanized top coal caving in Shuangshan coal mine. Cut the maximum value of the protective mining method. The results show that the fractured zone in the Shuangsan coal field is developed to turn on the surface aquifer, which makes the surface water flow into the underground well through the fissure zone is less likely.
