霍尔辛赫煤矿软煤层大采高采煤工艺的实践

Practice of great cutting height mining technology in soft coal seam in Huoerxinhe Mine

霍尔辛赫煤矿为高瓦斯矿井,主采的3#煤层为近水平煤层,平均厚5.65m。对该煤层设计时提出采用大采高采煤工艺及放顶煤采煤工艺,对两种采煤工艺进行技术经济比较,最后推荐了大采高采煤工艺。实践证明,大采高采煤工艺在该矿井取得了较好的技术经济效果。

Huoerxinhe Mine is a high-gas coal mine, in which the No. 3 main coal seam is a nearly level seam with the average thickness of 5.65m. In the mining designing of this seam, 2 methods of great cutting height mining and top-coal caving were presented. After making the economic and technical comparisons on the two mining technologies, the paper finally recommended the former. Practice proves that the great cutting height mining technology has achieved better technical and economic effectiveness in that mine.
