采取煤层分层煤样和可采煤样的准确率分析

The accuracy analysis on the selection of coal layered sample and recoverable coal sample

分析了铁法矿区煤层分层煤样准确率高于煤层可采煤样准确率的原因,同时介绍了采取井下煤层分层煤样的改进措施,并对今后煤层煤样的采取提出了建议。

The reason of the accuracy of the selection of coal layered sample is higher than that of recoverable coal sample was analyzed,and the improvement measures of selecting underground coal layered sample were introduced,then some suggestions for coal seam sample selection were given.
