华盛矿5号煤层可选性评定

Washability Assessment on No.5 Seam in Huasheng Coal Mine

通过对华盛矿5号煤层可选性评定,得出以下结论:当5号煤层精煤灰分8%时,δ±0.1含量为35.55%,可选性等级为难选;精煤灰分9%时,δ±0.1含量为25.66%,可选性等级为较难选;精煤灰分10%时,δ±0.1含量为17.25%,可选性等级为中等可选。

The washability assessment on No.5 seam in Huasheng Coal Mine comes to a conclusion that when the clean coal＇s ash content of No.5 seam is 8%, the content of δ±0.1 coal is 35.55%, the washability class is difficult to be selected, when the clean coal＇s ash content is 9%, the content of δ±0.1 coal is 25.66%, the washability class is more difficult to be selected, when the clean coal＇s ash content is 10%, the content of δ±0.1 coal is 17.25% ,the washability class is middle difficult to be selected.
