综采工作面矿压分布规律研究

Study on Distribution Law of Mine Pressure in a Fully Mechanized Mining Face

以山西省长治经坊煤业有限公司3-边角08综采工作面为研究对象,分析了该面的矿压分布监测方法及矿压分布规律。结果表明,老顶初压步距为30~39 m,周压步距为19~30 m,满足了现场支护需求。研究可为具有相似情况的矿井提供理论与实践的借鉴。

Taking the 3-corner 08 fully mechanized mining face of Changzhi Jingfang Coal Industry Co., Ltd. of Shanxi as the research object, this paper analyzed the mine pressure monitoring method and the mine pressure distribution law of the face. The results showed that the initial pressure step of the old roof was 30-39 m, and the cycle pressure step was 19-30 m, which satisfied the needs of on-site support. The study can provide theoretical and practical reference for mines with similar conditions.
