摘要
杭来湾煤矿根据302盘区30201工作面开采条件、巷道尺寸、支护方式及巷道布置情况,在工作面运输机巷及回风巷增加相应的监测设备,实施矿压观测。通过对矿压监测数据的分析,开展巷道支护效果的评价工作并预测工作面初次来压和周期来压覆岩垮落规律,保障安全生产。
Hanglaiwan Coal Mine according to the mining conditions,roadway size,support mode and roadway layout situation of the 302 plate area 30201 working face,the corresponding monitoring equipment is added in the transporter roadway and return air roadway of the working face,and the mine pressure observation is carried out.Through the analysis of mine pressure monitoring data,the evaluation of roadway support effect is carried out and the initial pressure and cycle of the working face are predicted to press the caving law of overlying rock to ensure safety in production.
