摘　　要：为了避免寺河矿5311综采工作面初采时期瓦斯超限,保证工作面安全高效回采,制定了通风、强制放顶、工作面尾巷钻孔、高位钻孔等一系列瓦斯防治措施。通过实践总结了高瓦斯突出矿井综采工作面初采瓦斯治理的技术和经验。核心技术包括采前通风“两进一回”、初采强制放顶、工作面尾巷钻孔抽放和高位钻孔抽放。初采时期工作面配风应合理,瓦斯抽采系统的设计应完整。本次实践为初采工程安全高效推进提供技术指导。In order to avoid the gas exceeding the limit during the initial mining period of the 5311 fully mechanized working face of Sihe Mine and ensure the safe and efficient mining of the working face,a series of gas prevention and control measures such as ventilation,forced roof caving,drilling of the end tunnel of the working face,and high-level drilling have been formulated.Through practice,the technology and experience of gas control in the fully mechanized mining face of high gas outburst mine are summa⁃rized.The core technologies include"two inlets and one return"for pre-mining ventilation,forced roof cav⁃ing in the initial mining,drilling and drainage in the end lane of the working face and drainage through high-level drilling.During the initial mining period,the air distribution of the working face should be rea⁃sonable,and the design of the gas drainage system should be complete.This practice provides technical guidance for the safe and efficient advancement of the initial mining project.
