采煤工作面初次放顶的技术与管理

Technology and control of first roof caving in coal working face

在采煤工作面初次放顶期间,通过对各类顶板矿压活动规律的观测,确定初次放顶的各项参数及计算方法。以指导初次放顶工作。采用统计学的方法进行了矿压分析和总结,根据初次放顶顶板情况进行了合理分类。并对矿压观测站的建立、矿压观测和压力显现情况提出了指导性的管理措施。对初次放顶的管理工作提出了具体的技术管理措施,并取得了明显的效果。

During the initial roof caving in the working face, through the observation of strata moving regularity of the different roof. We determined each section parameter calculating way of the first roof caving to guide the first roof caving work. We also introduced statistical way to analyze the strata in the initial roof caving and carried out reasonable classification. We put forward control measures for the establishment of strata observation station. We also proposed specific technical measures for the initial roof caving. Obvious results were obtained.
