大采深野青巷道支护工艺研究

Study on support technique of large mining depth and deep green roadway

根据九龙矿在大采深野青巷道支护的实践经验,总结出一套适合该类型巷道掘进支护的方法,显著加快了野青薄煤层的掘进准备工作,有效缓解了九龙矿采掘生产衔接紧张的局面,并以此为突破点完善了一套在不同地质条件下对不同支护材料的应用方法,提高了该矿的巷道顶板支护水平。

Based on practical experience of Jiulong Mine in support of arge mining depth and deep green roadway, a set of appropriate methods were summarized, which accelerated advancing preparation work of wild green thin coal seam and effectively mitigate tight cohesion in the mining production. A set of application methods of different supporting materials under different geological conditions were improved and roadway roof support level was enhanced.
