5月27日,安全监管总局、国家煤矿安监局印发《关于进一步加强汛期煤矿防治水工作的通知》(安监总煤调[2017]60号),内容如下。今年入汛以来,南方地区连续遭受强降雨,多地出现短时雷雨大风等强对流天气,防汛抗灾形势严峻。汛期是煤矿水害事故的易发期、高发期,大气降水明显增多,对地表水体、井下含水层和未封闭填实的小煤矿老空区进行补给,易导致煤矿水压升高、涌水量增大;持续强降雨,还可能导致地表水从井口倒灌井下,造成淹
On May 27, the General Administration of Customs and the State Administration of Coal Mine Safety issued the Circular on Further Strengthening the Work of Preventing and Controlling Water Disaster in Flood Season (安监 总 煤 调 [2017] No. 60) as follows. Since the beginning of the flood season this year, the southern region has been suffering from heavy rainfall in a row and many strong convective weather such as short-term thunderstorms and strong winds have taken place. The situation of flood control and disaster relief is grim. Flood season is a prone period of coalmine water accident, high incidence period, the atmospheric precipitation increased significantly, the surface water bodies, underground aquifers and open-fill small coal mines to provide empty area, easily lead to coal mine pressure, water increase Large; continued heavy rainfall may also cause surface water to be poured downhole from the wellhead, causing flooding
