在高沼气矿井进行综合机械化生产,由于生产的高度集中和高强度回采,使采区沼气涌出量大大增加,带来了通风工作的复杂化和增加了回采工作的危险性.应用沼气抽放是控制回采工作面沼气涌出的基本方法之一.实践证明,在打通一矿,采用沼气抽放方法,使工作面沼气量降低40%左右,在技术上是可靠的,经济上是合理的,它提高了工作面产量和作业的安全.
Because of the high concentration and high intensity of production, the emission of methane in the mining area greatly increases due to the comprehensive mechanization production in high-methane gas mines, which brings the complicated ventilation work and the increased danger of mining work. Is one of the basic methods to control the emission of methane from the working face.The practice proves that it is technically reliable and economically reasonable to break through the first mine and use biogas drainage method to reduce the methane gas in the working face by about 40% , It improves the work surface production and work safety.
