今年6月江苏地区煤矿掘进一队在掘进一材料道时,发生了一起顶板冒落的重大恶性事故。为吸取经验教训,我们对这次事故作了分析。 一、基本情况 该矿是1960年6月投产的已有30年历史的矿井。矿井原设计能力为60万吨,随着矿井逐年衰老,其中有两个煤系已基本采完,还有一煤系在开拓时遇到了奥灰水,现正进行注浆堵水,暂停开拓。“八五”期间计划列入矿务局衰老减产矿井,目前在现有老区找煤,进行复采,以延长矿井寿命。
In June this year, a group of coal mining teams in Jiangsu Province in the tunneling of a material road, a major accident occurred roof caving. In order to learn from the experience, we analyzed the accident. First, the basic situation The mine is put into operation in June 1960 30-year-old mine. The original designed capacity of the mine is 600,000 tons. As the mine ages year by year, two of the coal series have been basically finished mining. There is also a series of coal met in the pioneering Ordovician gray water, grouting and water blocking is now being suspended to open up. During the “Eighth Five-Year Plan” period, it plans to be included in the Mines Reduction and Mines Reduction Bureau of the Mines Bureau. Currently, it is looking for coal in the existing old districts for recovery so as to prolong the life of the mines.
