我国纵纤维石棉储量占整个石棉储量的20—30%,中长纤维石棉主要产于纵纤维棉脉。过去长期沿用坑探方法勘探纵纤维石棉,效率低,费用高。1984年,国家建材局地质研究所和西南地质公司合作,在四川石棉矿,对纵纤维石棉钻探取心进行了试验研究,并邀请全国储委和地矿部的专家到试验现场进行了检查验
China’s longitudinal fiber asbestos reserves account for 20-30% of the total asbestos reserves, medium-long fiber asbestos is mainly produced in longitudinal fiber cotton pulse. In the past, the exploration of longitudinal asbestos along the pit has long been inefficient and costly. In 1984, the National Bureau of Geology and Building Materials Institute of Geology and Southwest Geological Corporation, in Sichuan asbestos mine, drilling on the longitudinal fiber asbestos drilling conducted a study and invited experts from the State Reserve and the Ministry of Geology and Minerals to the test site inspection
