大采高浅埋煤层综采面矿压规律研究

 为了掌握泰山隆安公司大采高浅埋煤层综采面矿压显现规律,应用现场实测、理论计算等研究方法对泰山隆安公司8101工作面进行了矿压显现规律分析。研究结果表明：该工作面初次来压步距54～59m,平均55.5m;周期来压步距12.6～15.8m,平均14.16m;基本顶属Ⅳ级a类的来压非常强烈型;工作面支架的末阻力随初撑力呈线性增长;沿工作面方向压力具有中部较大、上部和下部较小的特点。

Study on the law of rock pressure of fully mechanized coal face of big mining height shallow mining depth in Taishanlongan company

In order to master the law of rock pressure of fully mechanized coal face of big mining height shallow mining depth Taishanlongan company, applied field measurement, theoretical calculation and other methods ,law of rock pressure of 8101 coal face is analyzed. The results show that First weighting interval length is 54 ~ 59 m, the average is 55.5 m; Periodic weighting length is 12.6 ~ 15.8 m, the average is 14.16 m; Basic roof belongs to a class of Ⅳ level of pressure very strong type; setting load of coal face support increased with resistance at the end of the cycle in the form of linear; The characteristics of coal face pressure is that the pressure in the middle of coal face is bigger and upper and lower is smaller.
