为了弄清厚松散层薄基岩条件下工作面顺槽顶板稳定性的影响因素,以顾北煤矿1212(1)工作面地质条件为工程背景,通过构建力学模型,得出厚松散层薄基岩条件下工作面顺槽顶板稳定性与各影响因素之间的关系。
In order to understand the factors that affect the stability of the roof along the working face under the condition of thick loose bedded bedrock, taking the geologic conditions of 1212 (1) face of Guibei Coal Mine as the engineering background, through the construction mechanics model, The relationship between the stability of the roof along the roof and various influencing factors under rock conditions.
