摘要 顺和煤矿2102工作面为永夏矿区首个深井开采工作面,为了了解工作面矿压规律,对首采工作面进行了现场矿压实测,并对工作面周期来压步距进行了分析。根据现场来压征兆并结合数据理论分析,确定了首采工作面顶板的周期来压步距及强度,摸清了顶板运动规律。研究为同类井田围岩条件下采煤工作面顶板控制及支护设计提供了理论依据。 2102 coal mining face in Shunhe Coal Mine was the first deep mining face in Yongxia Mining Area,in order to understand the law of mineral pressure in the working face,the field measurement of mineral pressure in the first mining face was carried out,and the pressure step distance in the working face was analyzed.According to the field pressure signs and the data theory analysis,the period of the top plate of the first mining face was determined to press step distance and strength,and the movement law of the top-plate was found out.The research provides a theoretical basis for the control and support design of the roof of coal mining face under the conditions of surrounding rock in similar well field.
