资料简介

节约煤炭很重要。 特别是煤炭开采区 储备是有限的。方面 重视煤炭节约 从计划阶段开始记账 确保最大恢复 在实施阶段。 矿井是用来开采煤炭的。 通过“露天”或 通过“地下”方法 视技术可行性而定 以及经济可行性。

Conservation of Coal is an important area particularly when our Coal reserves are finite. The aspect of conservation of Coal is taken into account right from the planning stage and maximum recovery is ensured during the implementation stage. Mines are designed to work the Coal seams either through 'opencast' or through 'underground' methods depending on the technical feasibility and economic viability.
