摘要
针对7311综放面瓦斯异常涌出和煤炭易自燃的特点和现实情况,提出并实施了采空区预埋管路抽放和局扇均压法相结合的瓦斯综合治理技术,配合加快工作面推进速度、减少采空区漏风和气雾阻化预防采空区煤自燃技术,并对各项技术措施的效果进行了总结、评价,探讨了采空区抽放、均压通风、工作面推进速度等各项技术参数。
Aimed at the abnormal gas gush at 7331 fully mechanized caving face, coal inflammable characteristic and actual circumstance, the gas comprehensive management technology of the goaf pipes-in fitting drainage and auxilary fan average pressure method is pointed out and carried out. In coordination with accelerating face advancing speed, reducing goal air leakage, aerial fog ignition inhibtion for goal coal inflammable prevention, each measure effect is summed up and appraised various technical parameters are discussed, such as goal drainage, average pressure ventilation and face advancing speed etc.
