摘要
沿空留巷技术作为一种高效的回采工艺,能够在提升煤炭回采率的同时改善矿井采掘交替衔接问题,提升矿井综合作业效率,对于矿井长久发展意义重大。以此为着手点,针对综放工作面沿空留巷技术开展分析,结合具体工程实际,在分析沿空留巷技术难点及其解决方法的基础上,对综放作业面沿空留巷支护开展综合分析,并对其应用效果做出实践分析,希望能够为其他矿井相似工程的开展提供借鉴与参考。
As an efficient mining technology,gob-side entry retaining technology can not only improve the coal recovery rate,but also improve the mining alternation connection problem,and improve the comprehensive operation efficiency of the mine,which is of great significance for the long-term development of the mine.Taking this as the starting point,this paper analyzed the gob-side entry retaining technology in fully mechanized caving face.Combined with specific engineering practice,based on the analysis of technical difficulties and solutions of gob-side entry retaining,it carried out comprehensive analysis on gob-side entry retaining support in fully mechanized caving face,and made practical analysis on its application effect,hoping to provide reference for similar projects in other mines.
