摘要
针对葫芦素煤矿21204首采工作面现场实际情况,分析了当前巷道布置方式的利弊,通过单巷掘进长距离通风的关键技术指标分析,成功设计并实现了单巷掘进4750m压入式通风,解决了长距离通风风阻大、风筒易脱节、地温高等问题,为单巷掘进长距离通风推广应用积累了宝贵经验。
Aiming at the actual situation of 21204 work face of Hulusu Mine, analyzed the advantages and disadvantages of the current roadway layout, through the analysis of key technical indexes of single tunneling long distance ventilation, successfully designed and implemented 4750 meter forced ventilation of single tunneling, solving problems such as high wind resistance when ventilating for long distance, easy disconnection, high ground temperature, provided valuable experience for single tunneling long distance ventilation application.
