综采放顶煤工作面矿压现显规律研究

Study on Regularity of Underground Pressure in Fully Mechanized Top Coal Caving Face

本文以山西某矿2603工作面为工程背景,对综采工作面开采引起的液压支架安全阀开启情况、超前支撑压力分布情况、巷道围岩变形等矿山压力显现情况进行分析,并根据矿压显现特征提出了一些有针对性的矿压控制措施,以期能为矿井安全生产提供一些有益的借鉴。

Taking the 2603 working face of a mine in Shanxi Province as the engineering background, this paper analyzes the opening of safety valve of hydraulic support, the distribution of advanced support pressure and the deformation of surrounding rock of roadway caused by mining in fully mechanized mining face, and puts forward some pertinent measures for controlling rock pressure according to the characteristics of rock pressure manifestation, so as to provide reference for mine. It provides some useful references for safe production of wells.
