软岩巷道预应力锚注支护技术的应用研究

Application of Prestressed Bolt Grouting Support Technology in Soft Rock Roadway

随着对煤矿的开采使矿井的深度不断增加,容易造成软岩巷道周围的围岩变形进而无法保证其稳定性,对某煤矿的深井软岩巷道预应力进行了分析,并对锚注联合支护形式的支护原理组成部分进行了说明,同时优化了巷道支护的形式和参数,这项应用研究策略对稳定软岩巷道的稳定性支护中起到了推动的作用,其他矿井软岩巷道的围岩支护应用也可以借鉴此种措施进行优化和改进。

With the continuous increase of the depth of the coal mine due to the mining of the coal mine,it is easy to cause the deformation of the surrounding rock around the soft rock roadway,which can not ensure its stability.The prestress of the deep soft rock roadway of a coal mine is analyzed,the supporting principle components of the bolt grouting combined support form are explained,and the form and parameters of the roadway support are optimized.This application research strategy has played a role in promoting the stability support of stable soft rock roadway.The surrounding rock support application of soft rock roadway in other mines can also learn from this measure for optimization and improvement.
