综放工作面长度及其矿压特征相关性研究

Research on Relativity between Face Length and Pressure Behavior Characteristics at Fully Mechanized Top Coal Mining

通过现场观测研究对长平煤矿综放工作面矿压显现特征、工作面长度与采场矿压显的影响相关规律进行了探讨,得出了综放工作面长度分别为90m和180m时,顶板压力显现差异不大以及工作面不同部位顶板压力差别明显的结论。为掌握综放工作面矿压规律并提出相应的控制措施提供了必要的参考依据。

Through site observation at Chang Ping Coal Mine,this paper probes into the relationship between face pressure behavior characteristics,face length,and strata stress of coal mine,and leads to the conclusion that when the fully mechanized top coal mining face is 90m long,the roof pressure behavior does not differ too much,while when the face is 180m long,the roof pressure behavior differ significant in different parts of the mining face.It offers essential reference for grasping pressure regularity and taking corresponding control measures.
