国内外成功经验表明,大采高工作面不仅能提高工作面单产、方便巷道布置、简化生产系统,而且能提高矿井资源采出率,是矿井高产高效集中生产的主要技术方向之一。以某矿大采高工作面开采技术条件为研究背景,利用现场实测、数理统计分析等方法,从顶板来压特征、支架载荷和超前支承压力分布规律等方面对大采高工作面矿压显现规律进行研究。为类似条件的工作面顶板控制提供了完善、可靠的资料,对解决工程问题具有实际指导意义。
The successful experience at home and abroad shows that the working face with large mining height can not only improve the yield per unit area, facilitate the layout of the roadway, simplify the production system, but also increase the recovery rate of mine resources. It is one of the main technical directions of high productivity and high efficiency centralized production in mines. Taking the technical conditions of the mining face of a large mining face as the research background, using the methods of field measurement, mathematical statistics and analysis, the strata behaviors of coal face with large mining height are revealed from the characteristics of roof pressure, the load of support and the pressure distribution of advance support The law of research. It provided perfect and reliable data for the roof control of working face under similar conditions and has practical guidance to solve engineering problems.
