A complex AnYuan coal mine gas occurrence, pouring amount is larger, only by ventilation method to solve the problem of gas overrun, so on the mine gas extraction is imperative. This paper introduces the basic situation of the mine， the necessity and feasibility of mine gas drainage are analyzed; Mine gas emission calculated by using separate source method，and analyzes the different gas drainage methods, design the gas drainage technology of mine; Through the analysis of the underground environment and extraction from the calculation of pipe diameter, determine the related parameters of extraction pipeline system; Tn calculating drainage system of the pipeline resistance and the gas pump flow and pressure, on the basis of choosing the suitable gas pump type. Tn this paper, the AnYuan coal mine gas drainage design，to reduce the gas emission when the mining face, reduce the gas accidents, to realize safety production play an important role. 关键字：瓦斯涌出、瓦斯抽放、瓦斯抽放系统、瓦斯抽放工艺 Key words: gas emission, gas drainage, gas drainage system and gas drainage technology TOC \o 1-5 \h \z HYPERLINK \l bookmark3 \o Current Document \h 1矿井概况 1 HYPERLINK \l bookmark4 \o Current Document \h 1.1工作面位S 1 HYPERLINK \l bookmark5 \o Current Document \h 1.2井田地形与气候 1 HYPERLINK \l bookmark6 \o Current Document \h 2矿井瓦斯抽放的必要性与可行性 2 HYPERLINK \l bookmark7 \o C
