【摘要】 在多年煤矿瓦斯理论研究及工程实践的基础上,总结提出了适用于煤矿瓦斯抽采指标考核要求的瓦斯抽采分类方法,即采前抽采、采中抽采和采后抽采.对各种抽采方法的基础理论进行了简要论述,并给出了具体的设计方法和技术参数.通过实例重点介绍了采前抽采煤层瓦斯的区域性瓦斯抽采方法,充分体现了"区域性防突措施先行"的工作原则.最后以淮北祁南煤矿为例,简要介绍了该矿通过瓦斯的综合抽采实现煤矿安全高效开采的先进经验.更多还原

【Abstract】 Based on theoretical researches pratical and applications of gas control for many years,we propose a classification method of gas extraction,which is suitable for evaluation standards and can ensure the gas extraction before,during or after coal seam mining.Then,we make a brief description about basic theories on gas control methods and give the concrete design method and technical parameters.In addition,we explain the method of regional gas extraction before coal seam mining using examples which follow the working principle of "regional gas control measures taken in advance".At last,based on the practice in Qinan coal mine of Huaibei mining industry group,we introduce advanced experiences to achieve safe and highly efficient mining using comprehensive gas extraction methods.更多还原
