乌拉尔铜业科学研究设计院用胶结法、电力疏干法和电化学法对中伏尔加人民经济委员会乌恰林采选公司“间湖”露天矿含水砂岩、砂砾岩和泥质岩石进行了人工固结和疏干的试验室试验。现将砂质岩石和泥质岩石试样的特性列于表1。为了固结砂砾岩石和砂质岩石,曾采用了МФ-17号的尿素树脂(尿素甲醛树脂),在凝固剂方面试用了草酸、盐酸、磷酸和氯化铵。为了制备固结用溶液,采用了树脂水溶液。经
Ural Copper Research Institute of Science and Technology by cementing, electric drying method and electrochemical method of the Volga County Economic Commission Wuqiaolin mining company “Lake” open pit water-bearing sandstone, glutenite and muddy rock artificial Knot and dry laboratory test. The characteristics of the sandy and shaly rock samples are listed in Table 1. In order to consolidate the gravel rock and sandy rock, МФ-17 urea resin (urea formaldehyde resin) was used, oxalic acid, hydrochloric acid, phosphoric acid and ammonium chloride were tested in the coagulant. In order to prepare the consolidation solution, a resin aqueous solution was used. through
