摘要
沿空留巷技术是一种绿色开采方法,但巷道支护问题是制约其发展的关键因素。针对屯兰煤矿18205工作面实际生产地质条件,提出了该条件下沿空留巷巷道的锚固技术和巷旁充填工艺。
Gob-side entry retaining laneway technology is a greenmining method,but the laneway support is a key factor restricting its development.In the light of the actual geological conditions of 18205 working face of Tunlan Coal Mine,this paper puts forward the gob-side entry retaining laneway anchoring technology and filling technology beside laneway.
