大倾角综放采场矿压规律及显现特点研究

Study on Ground Pressure Law and Appearance Characteristics of Fully Mechanized Caving Mining with Large Inclination Angle

为了确定某矿大倾角工作面矿压显现规律,根据工作面工况条件,制定了矿压观测方案,在工作面回风顺槽和运输顺槽内布置观测孔,对工作面超前压力进行观测,观测结果表明上部顺槽压力较大,需要加强超前支护。

In order to determine the law of strata pressure appearin g in a large inclined working face of a mine,according to the working conditions of the working face, a strata pressure observation scheme is formulated.Observation holes are arranged in the return air chute and the transportation chute of the working face, and the advance pressure of the working face is observed. The observation results show that the pressure of the upper chute is large, and the advance support needs to be strengthened.
