| 摘 要： | 山西省煤矿区岩溶陷落柱主要分布在汾河流域与沁水盆地两大区域,在汾河流域,自汾河上游向下,陷落柱分布密度呈现出依次增大的趋势;在沁水盆地,表现为以盆地北缘的阳泉矿区分布密度最大,其它矿区密度较小的特点。通过对山西省煤矿区陷落柱突水性的分析,总结出判断陷落柱突水的主要影响因素：一是陷落柱是否处于强径流带,二是陷落柱充填物的胶结与压实程度,三是陷落柱所在矿区的构造与水文地质条件,并以此为依据将矿区划分为突水可能性大、突水可能性中等和突水可能性小三种类型,成功实现了矿区陷落柱突水预测。预测结果表明,霍西煤田霍州矿区是导水陷落柱发育的重点矿区,潞安矿区深部开采时存在岩溶陷落柱突水的潜在可能性,其它矿区岩溶陷落柱导水事故发生的可能性较小。

| Abstract: | The karstic subsided columns in the coalmines in Shanxi province are mainly distributed in the Fenhe River valley and Qinshui Basin two regions.In Fenhe River valley,from upstream downwards,density of subsided columns has a trend of increasing;in Qinshui Basin,the maximum density is in the Yangquan mining area in north margin,while in other mining areas on the small side.After analyzed the water bursting property of subsided columns in Shanxi coalmines,summed up main impacting factors: the first is whether ... |
