摘　　要：综采放顶煤开采具有开采效率高、开采成本低等明显优势,但是由于综放开采中瓦斯涌出量较大,增加了综放开采的难度与危险程度。而选择使用高位巷抽采的方式,能够实现综放开采瓦斯浓度的有效控制。本文以某实际工程实际案例,从综采放顶煤工作面高位巷抽采关键技术要点分析入手,研究了综采放顶煤工作面高位巷抽采效果,并结合工程实践,提出了综采放顶煤工作面高位巷抽采应当注意的相关问题。Fully mechanized top-coal caving mining has obvious advantages such as high mining efficiency and low mining cost.However,due to the large gas emission in fully mechanized top-coal caving mining,the difficulty and danger of top-coal caving mining are increased.The effective comprehensive control of gas concentration in fully mechanized top-coal caving mining can be realized by selecting the way of high-level roadway drainage.In this paper,based on a practical engineering case,starting from the analysis of the key technical points of high-level roadway drainage in fully mechanized top-coal caving face,studies the drainage effect of high-level roadway in fully mechanized top-coal caving face,and puts forward the related problems that should be paid attention to in high-level roadway drainage in fully mechanized top-coal caving face in combination with engineering practice.
