焦作地处华北奥陶纪石灰岩天然地下水库群的枢纽中心,是世界第一流的大水矿区。解放三十多年以来,全矿区井下发生每分钟10吨以上突水53次,其中:每分钟100吨以上的突水4次;矿区淹井13次;局部地区被淹13次;每分钟最大一次突水量240吨。1983年矿区平均每分钟排水量512.4吨,吨煤排水量为60吨,吨煤排水费高达5.16元,矿区受水威胁的煤炭储量达6000余万吨,占可采储量的49.7％。地下水不但给矿井安全造成严重威胁,而且导致几个老矿井生产地区日益收缩,矿区生产能力急骤下降,生产发展受到严重阻碍。
Jiaozuo is located in North China Ordovician limestone natural underground reservoir group hub center, is the world’s first-class large water mining area. Since the liberation for more than 30 years, more than 10 tons of water inrush have occurred 53 times per minute downhole in the whole mine area, including 4 water inrushs of over 100 tons per minute; 13 flooded wells in mines; 13 submerged areas in some places; A water inrush of 240 tons. In 1983, the mine averaged 512.4 tons of water per minute displacement, 60 tons of tons of coal displacement, tons of coal drainage fees as high as 5.16 yuan, mine threatened by the coal reserves of 6000 tons, accounting for recoverable reserves of 49.7%. Groundwater not only poses a serious threat to the safety of mines, but also leads to the shrinking shrinkage of several old mine production areas, the drastic drop in the production capacity of mines and the serious impediment to the development of production.
