随着采煤安全技术的进步,目前倾斜采煤工作面的整体支护强度和安全系数已经有了很大的提高,尤其是在工作面的顶板安全防护上更是取得了很大的突破,但是由于矿下工作环境的复杂性以及地质运动的影响,局部冒顶事故仍然是时有发生。本文在分析引起局部冒顶的一半情况和预兆的基础上,分析做好倾斜采煤工作面冒顶的安全防护,希望对当前的采矿安全工作提供一点帮助。
With the progress of coal mining safety technology, the overall strength and safety factor of the overall inclined mining face has been greatly improved. Especially in the roof safety protection of the face, a great breakthrough has been made. However, due to the complexity of the working environment in the mine and the influence of the geologic movement, the accident of partial roof caving still occurs from time to time. Based on the analysis of half of the situations and warning signs that cause local roof caving, this paper analyzes the safety protection of roof falling in inclined coal mining face and hopes to provide some help to the current mining safety work.
