薄煤层炮采工作面矿压显现规律

Strata-pressure Behavior of Drilling and Blasting Coal Mining Face in Thin Seam

以孙义矿90101工作面为工程背景,通过对工作面回采过程中两巷及工作面的矿压检测,掌握工作面回采过程中坚硬顶板的矿压显现规律。以指导工作面的正常和安全生产,并为以后其他工作面的生产、支柱的选型和改进、规程和措施的制定提供坚实的依据。

Based on the No.90101 mining face in Sunyi mine,the strata pressure of roadway and coal mining face was monitored to achieve the strata-pressure behavior of drilling and blasting coal mining face under hard roof in mining process. The results show the reference for safe operating of mining face, creating regulation procedure, improving measures, as well as selection of support.
