摘要
在煤矿井下开采过程中,近距离煤层下部煤层复合顶板支护技术发挥着极为重要的作用,该技术的先进性与应用效果对生产的质量、效率和安全等方面都会产生重要影响。因此,结合当前井下实际开采情况,分析了近距离煤层下部煤层巷道位置的合理选择,确定了合理的近距离煤层下部煤层复合顶板支护技术支护方案及其质量控制措施,对该支护技术在实际开采中的应用效果及所带来的效益进行分析,为后期巷道顶板支护技术的发展提供一定的参考。
In the process of underground mining,the composite roof support technology in the underlying seam of the short distance coal seam plays a very important role.The progressiveness and application effect of this technology will have an important impact on the quality,efficiency and safety of production.Therefore,combined with the current underground actual mining situation,this paper analyzed the reasonable selection of the roadway location in the underlying seam of the short distance coal seam,and determined the reasonable support scheme and quality control measures of the composite roof support technology in the underlying seam of the short distance coal seam,and analyzed the application effect and benefits of the support technology in the actual mining,which provides a certain reference for the development of roadway roof support technology in the later stage.
