徐州韩桥煤矿夏桥井是具有五十多年开采历史的老矿井。矿井储量有限,而建筑物下却积压着大量的煤炭资源,即建筑物下可采储量占矿井总可采储量的近40％。因此,开展建筑物下采煤,解放建筑物下煤炭资源是韩桥煤矿急待解决的重要技术问题,也是延长矿井寿命的重要技术途径。为此,省煤矿研究所、徐州矿务局、韩桥煤矿三单位共同组建了“韩桥煤矿建筑群下采煤”课题组。 Hanqiao Xuzhou Hanqiao mine is more than 50 years of mining history of the old mine. Mine reserves are limited, but under the backlog of buildings is a large amount of coal resources, that is, the recoverable reserves of buildings account for nearly 40% of the total recoverable reserves of the mine. Therefore, carrying out coal mining under buildings and liberating coal resources under buildings are important technical problems to be solved urgently in Hanqiao Coal Mine and also an important technical way to prolong mine life. To this end, the Provincial Coal Research Institute, Xuzhou Mining Bureau, Han Qiao coal mine three units jointly set up a “Hanqiao Coal Mining Group under the mining group.”
