综采工作面初采阶段矿压显现特征研究

Study on characteristics of strata pressure in fully mechanized mining face

结合阳煤五矿8136工作面工程背景,对综采工作面初采阶段矿压显现特征进行了分析,及时掌控初采阶段的各种矿压形式,总结初采矿压显现规律,为同采区其他工作面提供预计经验及预测参数,同时将液压支架初撑力及工作阻力绘制成频率分布直方图来分析矿压显现特征,为同采区其他工作面矿压控制措施的制定提供数据参考,为类似地质赋存条件工作面的开采提供参考依据。

Based on the background of 8136 working face in Yangmei fifth Coal Mine, this paper analyzes the characteristics of strata pressure during the initial mining stage of fully mechanized coal mining face, and takes control of the various mining forms at the initial mining stage, summarizes the law of initial mining pressure, In order to provide the expected experience and prediction parameters for the other working face in the same mining area, the paper also draws the frequency distribution histogram of the initial support force and working resistance of the hydraulic support to analyze the characteristics of the strata behavior, which is the development of the mine pressure control measures in other mining areas And provide data reference for the mining of similar geological conditions of mining face.
