厚煤层综放开采技术、采场矿压与支承压力分布规律研究

Research on Fully-mechanized Mining Technology for Thick Seam and Regularities of Distribution of Stope Rock Pressure and Bearing Pressure

综放开采技术是煤矿企业实现高产高效的煤炭生产工艺。只有掌握和解决好综放开采过程中面临的一些关键技术和主要环节,包括:综放采场矿山压力,煤层顶板条件和结构,顶煤介质属性的变化、工作面煤体内支承压力分布规律、顶煤运移和破坏规律,顶板管理,架型选择,煤层的采高比等控制技术,才能确保煤炭生产企业的安全生产,从而有效提高综放开采的煤炭回采率。

Fully-mechanized mining technology is the production process realize the high production and high efficient of coal mine enterprise.Only grasp and solve the key technology and major process need to face during the fully-mechanized mining procedure,including the rockpressure of fully-mechanized mining stope,the roof condition and structure of coal seam,the change of top coal media properties, the regularitiesof bearing pressure of coal on the work face,and the displacement and failure law of top coal,roof management,selection of support and thecontrol technology of mining height of coal seam,can we ensure the safe production of coal mine enterprise and effectively increase the recoveryrate of fully-mechanized mining.
