在吉林省四平地区刘房子煤矿的煤系地层中夹有数层膨润土矿层,但从勘探至开矿九年来,未对其作为有用矿产进行分析鉴定,均以废石弃掉。一九八一年初,笔者从国内一些资料了解到钠基膨润土的用途广泛,国内外需用量逐年增加。因此,对刘房子煤矿中的膨润土进行了系统的研究,包括全岩化学分析、水质分析、阳离子交换分析、物性测试(吸兰、PH值、胶质价、膨胀倍数、湿压强度、干压强度、透气性等)、X射线
There are several layers of bentonite in the coal strata of the Liufangzi coal mine in Siping, Jilin Province. However, from exploration to mining nine years ago, it has not been analyzed and identified as a useful mine, and was discarded with waste rock. In early 1981, the author learned from some domestic data that sodium bentonite has a wide range of uses and needs both at home and abroad have been increasing year by year. Therefore, the bentonite in Liu house coal mine has been studied systematically, including whole rock chemical analysis, water quality analysis, cation exchange analysis, physical property test (suction blue, PH value, glial price, expansibility, wet compressive strength, Strength, breathability, etc.), X-rays
