基于多种监测手段的综采巷道超前支护优化

Optimization of Advance Support of Mining Roadway Based on Multiple Monitoring Methods

为保证矿井工作面回采过程中超前巷道的围岩稳定性,采用多种现场监测手段相结合的方法,对新疆某矿首采工作面超前支承压力分布规律和回采巷道围岩变形特征进行了研究,通过对观测结果综合分析,将工作面超前支承压力影响范围大致分为3个区域,并据此提出了合理的分区段巷道超前支护方式。

To ensure the stability of the advance supported roadway during the mining process, multiple field measurements were used to analyze the advance support pressure distribution law and the deformation characteristics of surrounding rock . Through the comprehensive analysis of the observation results, the influence range induced by the advance abutment pressure has been divided into three domains, and the corresponding advance suooort measures in different area has been pronosed.
