1、 I 摘摘 要要 煤与瓦斯突出，是在采掘过程中煤与瓦斯的突然喷出。这种喷出在短时间内产生很 大的冲击力量， 从煤层深处排出大量的煤和瓦斯， 并伴有强烈的声响和较大的动力效应， 例如摧毁巷道支护、破坏通风措施等。煤与瓦斯突出发生时，突出物能掩埋人体，涌出 的大量瓦斯可以造成瓦斯窒息事故，甚至引起瓦斯爆炸。因此，煤与瓦斯突出是煤矿井 下严重的自然灾害之一。为了减少和解除矿井瓦斯对煤矿安全生产的威胁，利用机械设 备和专用管道造成的负压，将煤层中存在或释放出的瓦斯抽出来，输送到地面或其它安 全地点的做法，叫做瓦斯抽放。 本设计结合已学的瓦斯基本理论，根据*煤层瓦斯的赋存特征、瓦斯的地质特征、 煤层瓦斯

2、含量分布规律等相关资料，运用综合分析法对该矿煤层瓦斯涌出量进行了实际 检测；并且通过对本采区的瓦斯涌出量预测以及对该采区的通风设计，瓦斯抽放设计与 瓦斯管理的深入了解，对该采区瓦斯防治工作进行了相关措施的设计。 关键词：关键词：矿井；矿井通风；瓦斯；瓦斯涌出量；瓦斯抽放 IV Abstract Coal and gas outburst, the spurt of coal and gas in mining p rocess. The ejection force greatly in a short time, emit large amounts of coal and gas from

3、 coal seam depth, and accompanied by strong noise and large dynamic effects, such as destruction of roadway, ventilation measures damage. The occurrence of coal and gas outburst, the bumps can be buried the body, a lot of gas emission can be caused by gas asphyxiation accident, even caused by gas ex

4、plosion.Therefore, the coal and gas outburst is one of the serious natural disasters in coal mine. In order to relieve the mine gas of coal mine production safety threat reduction and negative pressure caused by the use of machinery, equipment and special pipes, the coal seam in the presence or the

5、release of gas pumping out,transferred to the ground or other place of safety practices, is called gas drainage. This design is combined with the basic theory of gas already learned, relevant information according to the geologic characteristics of coal seam gas, nine coal mine of He-bi gas characte

6、ristics, coal seam gas content distribution, the actual detection of coal seam gas emission of the mine by using comprehensive analysis method; and the emission prediction of gas in this area and ventilation design the mining area, in-depth understanding of the design of the gas drainage and gas management, design of the relevant measures of working gas prevention and control the mining area.
