大同矿区综采40a开采技术研究
|
摘要
简要介绍了大同矿区40a来在坚硬顶板、坚硬煤层赋存条件下综采开采的顶板控制技术、开采工艺及瓦斯防治与煤层自燃的综合防治技术等方面的主要成就。针对煤炭资源越来越少的现状,对大同矿区今后几年的发展方向进行了展望。指出了应在1.2m以下薄煤层及20m以上厚煤层的开采技术、适宜残采矿井及新整合矿井实际情况的综采技术等方面取得突破,从而保障企业可持续发展。
Briefly introduced the main achievements of the roof control technology,mining technique and the gas prevention and control as well as the seam spontaneous combustion comprehensive prevention and control technology for the fully mechanized coal mining under the hard roof and hard seam deposit conditions in Datong mining area in the passed 40 years.According to the present status of the coal resources getting less and less,looked ahead on the development orientation of the near several coming years in Datong mining area.Pointed out that the breakthrough should be achieved at the mining technology for the seam thickness below 1.2 m and above 20 m,and the fully mechanized coal mining technology suitable for the coal mine with residual coal resources and the new integrated coal mine in order to ensure the sustainable development of the enterprise.
