摘　　要：以三元煤业4301综放工作面开采工艺选择为背景,通过引入模糊评价函数对顶煤冒放性进行综合评价,得出工作面顶煤冒放性属于Ⅱ类;分析了工作面回采工艺主要参数对放顶煤回采的影响,并确定了各参数具体数值,保证了矿井的高产高效,为类似条件下综放工作面回采工艺参数的选择提供了参考依据。With three yuan 4301 fully-mechanized caving coal mining technology choice as the background,by introducing fuzzy evaluation function of top-coal take put to carry on the comprehensive evaluation,it is concluded that mining top-coal take put sex belongs toⅡclasses;This paper analyzes the influence of the main technological parameters of the working face on the stoping of top-coal,and determines the specific values of the parameters,which ensures the high production and high efficiency of the mine,and provides a reference for the selection of technological parameters of the fully mechanized top-coal caving face under similar conditions.
