霍尔辛赫煤业工作面过空巷加固技术研究与应用

Research and Application of Cross-empty Lane Reinforcement Technology in Holsch Coal Working Face

霍尔辛赫煤业3601工作面回采期间面临安全过空巷的问题,现有液压支架工作阻力无法保证工作面安全顺利地通过空巷。通过理论分析、数值计算,设计采用打木垛和构建十字砌块墙的措施加固补巷,并在回采巷道内进行超前支护。现场实践表明,所采取的加固措施保证了工作面安全顺利地通过空巷。

The 3601 working face of Holsch Coal Industry faces the problem of passing through the empty lane safely during the mining period.The working resistance of the existing hydraulic support cannot guarantee the working face to pass through the empty lane safely and smoothly.Through theoretical analysis and numerical calculation,the measures of driving wooden crib and building cross block wall are designed to reinforce and mend the roadway,and the advance support is carried out in the mining roadway.The field practice shows that the reinforcement measures adopted ensure the working face to pass through the empty lane safely and smoothly.
