1、摘要摘要阳泉矿区位于沁水煤田东北边缘，是我国优质无烟煤基地之一，同时也是目前我国瓦斯涌出量较大的矿区之一。保安井田位于阳泉矿区西部，煤层埋藏相对较深，为煤与瓦斯突出矿井，瓦斯事故仍是影响矿井安全生产的突出问题之一。本论文以阳泉矿区保安煤矿井田8#、9#、15#煤层为研究区域，运用了瓦斯地质理论，结合矿区和井田地质构造特征，分析了地质演化及构造对瓦斯的控制作用；通过构造数学模型，分析了影响瓦斯赋存的主要地质因素，研究了矿井瓦斯地质规律；利用分源预测法和参数测定计算法对矿井瓦斯涌出量和突出危险区域进行了预测；根据矿井瓦斯地质研究成果优化了矿
2、井通风方式和通风系统，提出了保护层开采、通风瓦斯治理和大面积抽放的区域防突技术，合理确定了瓦斯本煤层、临近层、高抽巷、采空区和穿层抽采参数，提出了释放孔、预抽掘进工作面、边掘边抽、钻场抽放等综采工作面和综掘工作面的局部防突措施，加强了个人防护水平，强化了“四位一体”防突措施的落实和通风安全管理工作。研究成果为矿井瓦斯治理提供理论依据，为矿井瓦斯事故防治指明了方向，为矿井煤层气开发奠定了基础。关键词：瓦斯地质；瓦斯预测；瓦斯治理；瓦斯抽放Ⅰ河北工程大学硕士学位论文AbstractLyinginthenortheastofQinshuiCo
