成庄矿15号煤回采巷道支护技术研究

Study on Support Technology of the No.15 Coal Mining Roadway in Chengzhuang Mine

为了保证成庄矿15号煤的正常安全回采,以XV1307工作面为背景,通过地应力测试和围岩强度测试得到工作面地质力学参数,并对XV13074回采巷道进行了支护方案设计。现场监测结果表明,巷道两帮收缩量、顶板沉降量不大,巷道围岩完整性良好,支护参数设计合理可靠。

In order to ensure the normal and safe mining of the No.15 coal in Chengzhuang Mine,taking the XV1307 working face as the background,the geomechanical parameters of the working face are obtained by ground stress test and surrounding rock strength test,and the support scheme of the XV13074 mining roadway is designed.The field monitoring results show that the shrinkage of the two sides of the roadway and the roof settlement are small,the integrity of the surrounding rock of the roadway is good,and the design of support parameters is reasonable and reliable.
