运用“两步法”选择极薄煤层采煤方法

Selection of Mining Method for Very Thin Seam Using Two-step Selection

极薄煤层开采由于受作业空间限制,不仅作业环境恶劣,而且经济效益差,合理选择采煤工艺尤为重要。在对国内极薄煤层开采技术调查分析的基础上,总结归纳出回采工艺中主要工序的适用条件,运用价值工程理论,提出了科学、系统的选择方法,可供极薄煤层开采矿山及设计单位工作中借鉴。

Due to space limitation,thin seam mining operation is not only difficult to operate but also has poor economic returns. Based on the investigation and analysis of the mining technology of ultra- thin coal seam in China,the applicable conditions of the main processes in the mining process are summarized in this paper. A scientific and systematic selection method is put forward by using the theory of value engineering,which can be used for reference in the mining of thin coal seam and the design.
