大采高技术推广能效评价与经济分析计算

Evaluation and Economic Analysis on Large-mining-height Technology Generalization

厚煤层大采高采煤工艺以产量高、回采率高、成本低等特点得到广范应用。王庄煤业引进大型综采设备,采用一次采全高采煤工艺,从回采率、工效率、掘进率等方面进行了计算分析,并评价了厚煤层一次采全高的巨大经济效益。

The large-mining-height technology of thick coal seam is widely used with features like high yield,high recovery rate,and low cost.Wangzhuang Mine introduced large fully-mechanized mining equipments and adopted fully-mechanized coal mining with all height mined at one time.The paper evaluates the economic benefit of the mine in terms of recovery rate,energy/efficiency rate,and drivage ratio.
