| 摘 要： | 以沈煤集团红菱煤矿保护层开采为工程实例,通过开采11#煤层,对存在煤与瓦斯突出的7#煤层和12#煤层进行卸压,研究保护层开采后采动裂隙分布规律。阐述了含瓦斯煤的力学特性:通过相似模拟实验,用散斑法对保护层开采过程中采动裂隙分布规律及煤岩体的渗透性进行了分析。

| Abstract: | Based on engineering example of protective layer mining in Hongling coal mine of Shenyang Coal Group,the mining-induced fracture distribution has been studied.And the mechanical property of coal containing gas is expounded.By similarity simulation experiment,we analysis the mining-induced fracture distribution and permeability of coal and rock mass near protective layer mined by speckle method. |

| Keywords: | protective layer coal and gas outburst mining-induced fracture similarity simulation |
