冀鲁豫石炭二迭纪煤田在开发过程中地下水害问题十分突出。煤层底板含水层,特别是中奥陶世石灰岩含水层的突然涌水,往往造成矿井淹没,迫使矿井进行大量排水。因此,研究底板突水条件,预测突水点部位,以便采取预防地下水突入矿井的技术措施,是贯彻以防为主,综合治理地下水害原则的技术途经之一。对于这一问题,如开滦、峰峰、邯郸、焦作、
The problem of groundwater damage during the development of the Permian Carboniferous Permian coalfield in Hebei, Henan and Henan Provinces is very prominent. The sudden water influx from the coal seam floor aquifer, especially the middle Ordovician limestone aquifer, often causes the mine to drown and forces the mine to carry out heavy drainage. Therefore, it is one of the technical ways to carry out the principle of prevention first and to comprehensively control the principle of groundwater damage by studying the water inrush conditions of the floor and predicting the location of the water inrush point so as to take measures to prevent the intrusion of groundwater into the mine. For this issue, such as Kailuan, Fengfeng, Handan, Jiaozuo,
