我国煤矿是煤与沼气突出(以下简称突出)威胁严重的国家之一,目前,全国约有突出危险矿井150多对,突出瓦斯的种类基本为沼气,但二氧化碳突出在个别矿井也发生过。我国对消除突出灾害十分重视,除作为安全技术的重要课题,大力进行试验研究外,在《煤矿安全规程》中对防治突出措施作了明确的规定 China’s coal mines are one of the countries with serious threats of coal and methane (hereinafter referred to as “prominence”). At present, there are over 150 pairs of prominent dangerous mines in the country, with the most prominent types of methane being biogas. However, the prominence of carbon dioxide has also occurred in some mines. China attaches great importance to the elimination of outstanding disasters, except as an important issue of safety technology, vigorously carry out experimental studies, in the “Coal Mine Safety Regulations” on the prevention and treatment of outstanding measures made a clear provision
