大倾角综放面矿压显现规律研究

Study on Large Inclined Angle Fully Mechanized Caving Face Mine Pressure Behavior Law

为了研究大倾角煤层在综放开采工艺下的顶板矿压显现规律,对实际矿井急倾斜综放工作面进行现场监测研究。根据监测数据分析可知,工作面压力上部压力最大,下部最小,来压步距与之相同,同时可以得知,工作面推进速度越慢,支架的工作阻力越大,为以后大倾角综放工作面支架选型提供技术经验借鉴。

In order to study large inclined angle fully mechanized caving face mine pressure behavior law, the actual mine steeply inclined fully mechanized caving face field monitoring research was conducted. According to the monitoring data analysis, upper working face pressure was biggest, the lower minimum, same with pressure step, in the meantime, it was concluded that the slower the working face advancing speed, the greater the working resistance of support, which provided technical experience and reference for large inclined angle fully mechanized caving face support selection.
