摘要
以长城三矿一工作面的实际开拓与开采情况为例,采用现场实际监测的手段重点对该工作面实际开采期间的应力分布与留巷巷道的顶板、底板的运动等情况进行了监测,分析了留巷受采动影响的矿山压力显现与响应特征,以期监测结果与分析结果能够较好地了解该矿与该工作面留巷的矿压响应规律,以期为类似工程地质条件工作面采掘等提供有利的重要的理论参考和工程实用价值.
Abstract
Taking the actual development and mining situation of the first working face of the Great Wall No.3 Mine as an example,the stress distribution during the actual mining period of the working face and the movement of the roof and floor of the retained roadway were mainly monitored using on-site monitoring methods.The characteristics of the mining pressure manifestation and response of the retained roadway affected by mining were analyzed.The monitoring and analysis results are expected to provide a better understanding of the mine pressure response law between the mine and the remaining roadway of the working face,in order to provide favorable theoretical references and practical engineering value for similar engineering geological conditions such as mining in the working face.
