采动影响下深井高地压沿空巷道支护研究与实践

Research and Practice in Deep Mining Under the Influence of High Pressure Gob-side Entry

试验巷道处于复杂的围岩环境中,通过经验法和数值计算法对巷道围岩进行分析,提出了预留断面、提高煤柱帮支护强度和强化顶板的支护对策,经现场监测表明,最终的支护设计是合理的,达到了巷道的正常使用要求,也表明将经验法、数值计算法和现场监测相结合,是优化巷道支护设计的有效手段。

Test of the rock tunnel in a complex environment, through experience, method and numerical calculation of the roadway sur- rounding rock analysis, put forward the reserved section, to help improve the coal pillars supporting the roof strength and strengthen supporting measures by the on - site monitoring indicate that supporting the final design is reasonable, and reached the normal use of roadway requirements, but also indicated that he would experience in method, numerical calculation and on - site monitoring of the combination is to optimize the roadway design of effective means.
