| 摘 要： | 急倾斜厚煤层开采时发生的水媒体溃泄是一种新的矿井灾害.为了有效的防止水煤体溃泄灾害的发生,介绍了水煤体溃泄灾害发生的条件,实验测试了水煤体的物理力学性质,进行了围岩变形相似材料模拟实验,分析了水煤体溃泄的机理,提出了防治水煤体溃泄的工程措施.结果表明,通过对煤粉、水源、水煤体堆积体积和所处力学条件这几个水煤体溃泄的主要因素的有效控制既能有效的防止水煤体溃泄灾害的发生.

| Abstract: | Water-coal mixture burst is a new mine disaster in exploiting steeply-inclined thick coal seam mining.In order to effectively prevent of water-coal body from bursting,we tested the physical and mechanical properties,performed the similar material simulation for surrounding rock deformation,analyzed the mechanism of water-coal outburst,and proposed countermeasures for preventing the burst from taking place.The results show that water-coal body burst can be avoided by effectively controlling major factors suc... |
