1 概述所谓煤矿资源指的是煤炭和与煤炭共生或伴生矿产资源。我国煤炭资源十分丰富,含煤建造厚度大,成煤时代齐全,煤的形成环境与后期改造又复杂多样,因而在煤层及其围岩中共生及伴生着丰富的矿产资源,尤其是非金属矿资源。已发现有开采价值的矿产有几十种,如耐火粘土、高岑土、膨润土、硅藻土、石墨、硫铁矿、油页岩、石膏、菱镁矿、滑石、硅灰石等。在煤层中还赋存有相当丰富的伴生元素,如钒、铀、钼、铜、钴、金、银、
1 Overview The so-called coal resources refers to the coal and co-occurrence of coal or associated mineral resources. The coal resources in our country are very rich. The thickness of coal-bearing construction is large and coal-forming age is complete. The formation environment and post-transformation of coal are complex and diverse. Therefore, there are abundant mineral resources in the coal seam and its surrounding rock, especially non-metallic mineral resources . It has been found that there are dozens of minerals with mining value, such as refractory clay, high-concentrated earth, bentonite, diatomaceous earth, graphite, pyrite, oil shale, gypsum, magnesite, talc and wollastonite. In the coal seam there are also abundant associated elements, such as vanadium, uranium, molybdenum, copper, cobalt, gold, silver,
