一、问题的提出 1981年12月24日,平顶山五矿戊二采区发生了一起重大的瓦斯煤尘爆炸事故。82年元月河南省煤炭管理局通知焦作矿院派人参加事故调查分析。 调查中发现:平五矿是用水除尘的矿井,有较完善的防尘洒水系统和管理制度。然而瓦斯引爆,导致煤尘多次连续爆炸的客观事实,给我们提出了下列问题:是防尘洒水系统不完善,还是水力除尘本身存在某种不足?带着这些问题我们拟对平五矿巷道的煤尘沉积情况进行全面调查。但平五矿当时巷道破坏严重,除了洒水防尘系统及管理制度等可在五矿调查外,有关煤尘沉积情况等内容已无法进行。据了解,平六矿也是用水除尘的矿井,其技术措施与管理制度也基本相
First, the issue put forward December 24, 1981, Pingdingshan Minmetals second mining area occurred a major gas coal dust explosion accident. In January 82, Henan Coal Administration informed Jiaozuo Mining Group to participate in the accident investigation and analysis. Survey found: Ping Minmetals mine dust water, there is a sound system of dust and water and management system. However, the fact that gas detonation leads to continuous explosion of coal dust for many times has given us the following questions: Is the system of dust-proof and water-sprinkling imperfect, or is there some deficiency in hydraulic dust-removal? With these problems, Of the coal dust deposition conducted a comprehensive investigation. However, the mine was severely damaged at the time of Ping-Min Mine. Except for sprinkler dust-proofing systems and management systems, which can be investigated at Minmetals, the contents of dust deposits and other related issues have not been carried out. It is understood that Pingli Mine is also a dust mine dust, and its technical measures and management system is also the basic phase
