综放沿空留巷围岩控制分析

Surrounding Rock Control Analysis of Gob-side Entry Retaining in Fully Mechanized Caving

沿空留巷作为一种能显著提升煤炭回采率的工艺手段,在国内各大矿区有着广泛应用。但随着回采深度的增加,沿空留巷的围岩控制难度不断增加,影响煤矿生产安全。以此为着手点,结合具体工程实际,在分析沿空留巷围岩控制难点与对策的基础上,对相应的沿空留巷支护技术进行了分析总结,希望能够为矿井生产的安全开展提供借鉴与参考。

Gob-side entry retaining,as a technological means to significantly improve coal recovery,has been widely used in major mining areas in China.However,with the increase of mining depth,the difficulty of surrounding rock control of gob-side entry retaining is increasing,which affects the safety of coal mine production.Taking this as a starting point,combined with the actual engineering,this paper analyzed the difficulties and countermeasures of surrounding rock control of gob-side entry retaining and summarized the corresponding support technology for gob-side entry retaining,hoping to provide reference for the safe de-velopment of mine production.
