关于开采七台河矿区极薄煤层工业指标的探讨

研究了煤层赋存的地质特征与极薄煤层的开采工艺,结合国内、外极薄煤层的开采现状,对影响煤层开采的主要因素逐类进行分析,筛选出影响综合评价的主导因素,界定了非经济可采煤层的技术指标,对七台河地区极薄煤层开采的工业指标提出了建议,可为政府在矿产资源管理与制定相关政策方面提供参考性意见。

Discussion on the Industrial Index of the Very Thin Coal Seam Exploitation in Qitaihe Coal Mine Area

The geological characteristics of coal beds occurrence and the mining technique of very thin coal seams are studied in this paper.By combining the domestic and international actuality on very thin coal seam mining,the influence factors on the seam mining are analyzed step by step,the decisive factors which affect comprehensive evaluation result are sorted and selected,the technique guide line for the uneconomically minable coal seam is defined and the industrial index of the very thin coal seam exploitation in Qitaihe Coal Mine area is proposed.These are very beneficial to the mineral resources management and associated policy making.
