本科论文摘 要中国是每年的煤炭生产量约是世界煤炭总产量的一半，是世界上最大的煤炭生产国家。我国目前正处于社会发展的高速阶段，对煤炭等化石能源的依赖性日益强烈，再加上煤炭是我国最主要的化石能源，储量极为丰富，在国家能源结构中有着很高的战略地位，其消费比重近几年都在 70%左右，可见在未来很长一段时间里，我国的主体能源依旧会是煤炭。但纵观中国发展全局，中国的地质状况多样且复杂，工业化发展导致煤炭需求量大大增加，因此，生产和发展的矛盾突出，影响着中国国民经济的稳定持续发展和地区安全。国内近期以来煤矿产业发展迅速，矿井瓦斯涌出量随着煤矿开采力度的加深增加，同时煤矿安全问题也越来越受到人们的重视。我国许多煤矿在开采过程中都存在各式各样的瓦斯突出等危险状况，所以为了煤矿开采的安全有效，瓦斯抽采已然成为了及其重要的环节，尤其是高瓦斯煤层的开采，而且瓦斯的抽采还能提高瓦斯的利用率，为环保做出很大贡献，因此，为了安全生产，我们需要建立一个完善高效的瓦斯抽采系统。关键词：煤层；高瓦斯矿井；瓦斯涌出；瓦斯抽采Abstract本科论文China's annual coal production is about half of the world's total coal production and is the world's largest coal producer. China is currently at a high-speed stage of social development, and its dependence on fossil energy such as coal is becoming stronger and stronger, In addition, coal is the most important fossil energy in China, and its reserves are extremely rich. It has a high strategic position in the national energy structure. Its consumption proportion is about 70% in recent years. It can be seen that in a long period of time in the future, China The main energy source will still be coal. However, looking at China's overall development situation, China's geological conditions are diverse and complex, and industrialization has led to a significant increase in coal demand. Therefore, the contradiction between production and development affects the national economy and social security.In recent years, the coal mine ...
