采煤工作面矿压显现规律影响因素分析

Analysis on Influencing Factors of mine pressure behavior in coal face

在采煤工作面回采过程中,能够导致井下事故发生的危险因素多,其中矿压显现是严重影响工作面生产和井下人员安全的危险因素之一。为了减小矿压显现强度,避免强矿压的发生,保证井下人员的安全和生产工作的正常进行,必须要对矿压显现规律的影响因素进行研究分析,其主要包括:工作面推进速度、开采深度、工作面长度、采高与控顶距等。

In the coal mining face, there are many risk factors that can lead to the occurrence of downhole accidents, among which the mine pressureisoneof the risk factors that seriously affect the production of the face and the safety of the miners. In order to reduce the strength of mine pressure behavior, avoid the occurrence of strong mine pressure, ensure underground personnel safety and normal production work, influence factors for regularity of mine pressure must be analyzed, which mainly includes： the speed of working face, mining depth, length of working face, mining height and roof control distance, etc.
