台头矿2S224工作面矿压监测与结果分析

Observation and Result Analysis of Underground Pressure of2S224 Mining Face in Taitou Colliery

通过对台头矿2S224工作面顶板破碎度、煤壁片帮、巷道变形和支架载荷的现场观测,分析了该工作面的矿压显现规律,得出了工作面的周期来压步距;同时探讨了工作面顶板垮落模式和出现端头悬顶的原因。研究表明提高该工作面推进度是降低顶板破碎度和减少片帮的有效措施。

This paper analyzed underground pressure behavior rules and periodic weighting pace of 2S224 Mining Face of Taitou Colliery on the basis of observation data of roof broken degree, coal wall spalling, roadway deformation and support load. It also discussed roof falling mode and cause of roof hanging at end head. Result showed that improving mining speed was an effective measure for reducing roof broken degree and decreasing wall spalling.
