摘要 为缓解鹿台山煤矿矿井采掘接续紧张的状况,同时减少相邻工作面区段巷道掘进工程量,降低掘进工程费用,确保2203工作面顺利接替,对2202工作面轨道顺槽进行沿空留巷试验。根据巷道围岩地质条件,通过理论分析,并结合切顶卸压预裂爆破顶板技术,提出了切顶卸压沿空留巷支护方案。通过连续观测工作面回采期间的巷道围岩变形特征,总结了切顶卸压沿空留巷的矿压显现规律。分析结果对于鹿台山矿沿空留巷实践有一定的参考价值。

Abstract: In order to alleviate the tension situation of continuous mining of Lutaishan Mine,reduce the amount of roadway tunneling in the adjacent working face sections and the cost of tunneling,and ensure the smooth replacement of 2203 working face,the test of god side entry retaining along the track of 2202 working face is done.According to the surrounding rock geological conditions of the roadway,and based on theoretical analysis and pre-split blasting roof technique,the supporting scheme of gob side entry retaining by roof cutting and pressure relieving is proposed.The mine pressure development regularity in gob side entry retaining by roof cutting and pressure relieving is summarized by continuously observing the surrounding rock deformation data of the roadway during stoping process.The above study results can provide reliable reference for the practice of god side entry retaining of Lutaishan Mine.
