为了提高资源回收率,提出将短壁连采工艺应用于解放边角煤呆滞煤量的生产实践中。通过采用理论分析、数值模拟和工程实测相结合的研究方法,结合某矿边角煤赋存地质条件,对短壁采场的矿压显现和顶板运动规律进行分析研究,得出采取适合的顶板控制措施实现对坚硬顶板的有效控制是短壁连采工艺实现安全回采的关键。
In order to improve the recovery rate of resources, it is proposed to apply the short-wall continuous mining technology to the production practice of liberating coal with sluggish coal bed. By using the research methods of theoretical analysis, numerical simulation and engineering measurement, combined with the geological conditions of coal deposit in a coalmine, the strata pressure behavior and roof movement in shortwall mining stope are analyzed and studied. Control measures to achieve effective control of the hard roof is short-wall mining technology to achieve the key to safe mining.
