"两硬"条件下薄煤层机械化开采实践与发展方向

回顾了大同矿区在薄及较薄煤层机械化开采技术上的发展历程，介绍了我国薄煤层开采技术发展情况，针对大同矿区“两硬”（顶板硬、煤层硬）煤层条件和较为复杂地质条件的特点，提出了适合大同矿区薄煤层机械化开采的发展方向。

The Practice and Development Direction of the Mechanical Mining in Thin Coal Seam under the Condition of Hard Roof and Hard Coal Bed

This paper reviews the development history of Datong Mining Area in mechanical mining technology in thin and thinner coal seams,introduces the development of the mining technology for the thin coal seams in China,and in the light of the coal-bed conditions of the hard roof and hard coal bed and the more complicated geological conditions,puts forward the development direction of the thin coal-bed mechanical mining technology that is suitable to the conditions of Datong Ming Area.
