由兖州煤业股份有限公司和中国矿业大学共同承担的超高压奥灰水上采煤水害预测评价研究项目,在兖州煤田煤层埋藏最深的东滩矿取得突破。东滩矿下组煤资源储量1.47亿t,底板奥灰水压为兖州煤田之最,亦为迄今为止国内已开采矿井中奥灰水压最大的矿井。该项目结合东滩矿深
By Yanzhou Coal Mining Co., Ltd. and China University of Mining jointly undertake ultrahigh-pressure coal mining water hazard prediction and evaluation project, the Yanzhou coal mine buried the deepest breakthrough in Dongtan mine. Dongtan coal mine reserves of 147000000 t of reserves, the bottom of the Austrian gray water pressure is the most Yanzhou coalfield, but also for the domestic mining has been the largest coal mine pressure gray water pressure. The project combined with deep mine in Dongtan
