铜龙煤矿煤层、煤质特征及工业用途分析

Analysis of Coal Seams,Coal Quality Characteristics and Industrial Use in Tonglong Coal Mine

根据铜龙煤矿勘探成果资料显示区范围内含有可采煤层3层(5号、7号及12号),总资源储量为3489万t,3层可采煤层均为较稳定煤层,且构造简单,开采技术条件中等,具有较强的经济开采价值。本文通过收集区域和铜龙煤矿勘探工作中所取得的煤层、煤的物理性质、煤岩特征、煤的化学特征、煤工艺性能等相关地质资料进行综合分析,得出矿区范围的5号、7号及12号均属无烟煤3号(WY3),煤层均属于中高硫煤、中灰煤、特低挥发分煤,适用于动力用煤及民用煤,为今后铜龙煤矿的煤炭资源开发利用和研究提供了基础依据。

According to the exploration results of Tonglong Coal Mine,there are three layers of minable coal seams(No.5,No.7,and No.12)within the data display area,with a total resource reserve of 34.89 million tons.The three layers of minable coal seams are relatively stable coal seams,with simple structures and moderate mining technology conditions,and have strong economic mining value.This article conducts a comprehensive analysis through the collection of relevant geological data such as coal seams,coal physical properties,coal petrological characteristics,coal chemical characteristics,coal process performance and others obtained from regional and exploration work in Tonglong Coal Mine.It is concluded that the No.5,No.7,and No.12 coal seams in the mine area range all belong to anthracite coal No.3(WY3),and the coal seams belong to medium high sulfur coal,medium ash coal,and ultra-low volatile coal,which are suitable for power used coal and civilian coal,and provides a basic basis for the development,utilization,and research of coal resources in Tonglong Coal Mine in the future.
