顿巴斯矿区内,许多矿是在复杂地质条件下进行凿井的。它们的井筒中都有高于正常的涌水量,这使凿井的劳动卫生保健条件恶化、凿井工程的进度减慢,并提高凿井工程的造价及增加井筒施工、运行时的排水费和修理费。目前,防治涌水的主要方法之一,对岩层的堵水而言,仍停留于用水泥沙浆及粘土水泥沙浆堵水。可是,实际上只研究了中硬、坚硬裂隙岩层使用这两种沿浆堵水的注浆工艺。对小裂隙、毛孔砂岩遏制水的尝试,终因粘土水泥微粒渗透能力低、没有导
In the Donbas mine area, many mines are drilled in complex geological conditions. Their wellbores have a higher than normal water inflow, which aggravates the conditions for sanitation and sanitation of the shaft sinking, slows down the progress of the shaft sinking work, increases the cost of the shaft sinking work and increases the drainage costs during well construction and operation Repair costs. At present, one of the main methods of preventing and controlling gushing water is to stop water plugging with cement mortar and clay cement mortar in terms of water blocking. However, in fact, only the study of the hard, hard fracture rock formation using these two grouting along the water plugging process. Attempts to contain small fractures and pores in sandstone contain water because of the low permeability of clay-cement particles,
