针对丁集煤矿东三13-1皮带机大巷及东三13-1轨道大巷掘进矸石均进入出煤系统,造成选煤厂筛分洗选困难,洗选成本增加,煤灰分高,销售价格低等问题,提出并实施建立地面矸石仓及井下掘进头面卧式矸石仓,矸石进入地面矸石仓,煤进入选煤厂洗选,解决选煤厂洗选矸石难度、降低煤灰分提高煤质、降低生产成本。
For Dingji coal mine Dongsan 13-1 belt machine lane and Dongsan 13-1 track alley excavation gangue all entered the coal production system, resulting in the difficulty of coal preparation plant screening, washing costs increased, high ash coal, sales Low prices and other issues, put forward and implement the establishment of the ground waste rock silo and underground head face horizontal gangue warehouse, gangue into the ground waste rock, coal into the coal preparation plant washing, coal preparation plant to solve the difficulty of washing gangue, coal ash to reduce the quality of coal ,reduce manufacturing cost.
