金山煤矿综放开采技术应用可行性分析

Feasibility Analysis of Fully-mechanized Caving Mining Technology in Jinshan Colliery

金山煤业有限公司12号煤层服务年限不足1年,为保证生产的正常接续,着手准备开采13号煤层;本文对影响放顶煤开采的水害、瓦斯、煤层赋存条件、顶板性质以及自燃性等影响因素进行了综合分析,运用采场顶煤冒放性评价方法对工作面顶煤冒放性进行计算,其13101综放工作面顶煤冒放性评价结果为“好”;对13号煤层进行了放顶煤开采可行性初步论证,认定13号煤层可以采用放顶煤开采技术。

To make preparation of mining No.13 coal seam in Jinshan Colliery,the paper makes a feasibility demonstration of top coal caving mining by comprehensive analysis of influencing factors,such as water disaster,gas,coalbed occurrence condition,roof property and spontaneous combustion at 13101 working face,which is proved to be practicable.
