兴隆矿开采煤层的可选性评定

The Washability Assessment on the Working Seams in Xinglong Coal Mine

通过对兴隆矿开采煤层可选性评定,得出结论:该矿开采煤层为2号和5号煤层;2号煤层当浮煤灰分为20%时,可选性等级为难选,当浮煤灰分为30%时,可选性等级为较难选;5号煤层当浮煤灰分为8.45%时,可选性等级为易选,当浮煤灰分为19.18%时,可选性等级为中等可选。

The washability assessment on the working seams in Xinglong Coal Mine comes to a conclusion that the working seams of Xinglong Coal Mine are No.2 and No.5 seams; when the float ash content Of N0.2 seam is 20%, its washability class is difficult to select, when the float ash content of N0.2 seam is 30%, its washability class is moredifficuh to select; when the float ash content of N0.5 seam is 8.45%, its washability class is easy to select, when the float ash content of N0.5 seam is 19.18%, its washability class is middle difficult to select.
