回忆在五十年代初,抚顺煤矿的煤炭产量要大幅度增加,可是遇到的最大困难就是矿井瓦斯问题,它象一只无形的拦路虎阻碍着生产的发展。象抚顺这样一个高沼气矿井,单纯地靠增加风量的办法来解决回采中的瓦斯问题是不现实的。为保证矿井安全,发展煤炭生产,抚顺煤矿于1952年7月1日试验成功了在本层煤中预先抽放瓦斯的方法,从而征服了自然,战胜了煤矿这一凶恶“敌人”,并使之“变害为利”,造福于人民。一、现行瓦斯抽放方法1.预抽瓦斯所请预抽,就是按照开采采区设计抽放率要求和实际抽出率的大小,
Recall that in the early 1950s, coal production in Fushun Coal Mine would increase substantially. However, the biggest difficulty encountered was the problem of gas in mines. It was like an invisible stumbling blocks impeding the development of production. As a high-fushuang Fushun coal mine, simply by increasing the air volume to solve the problem of gas in the mining is not realistic. In order to ensure mine safety and develop coal production, Fushun Mine successfully tested the method of draining methane in this layer of coal in advance on July 1, 1952, thus conquering nature and defeating the vicious “enemy” of coal mines and making The “change for the benefit of” for the benefit of the people. First, the current method of gas drainage 1. Pre-pumping gas pumping please pre-pumping, that is, in accordance with the mining design requirements of mining extraction rate and the actual rate of withdrawal of the size,
