复杂厚煤层条件工作面回采方法研究
|
摘要
以复杂厚煤层条件工作面回采方法为对象开展探究,结合工程实际,在分析急倾斜厚煤层回采面实际状况的基础上,从工作面布置、回采工艺和坚硬顶板处置三方面对所采用的斜切分段综放工艺开展讨论,并对其实际应用效果做出分析。结果表明,斜切分段综放工艺实现了急倾斜厚煤层的高效安全回采,希望能够为其他矿井提供借鉴与指导。
Taking mining method of working face with complex thick coal seams as the object, combining with engineering practice, based on the analysis of the actual situation of the mining face of steeply inclined thick coal seams, this paper discussed the chamfered section fully mechanized caving process from three aspects of working face layout, mining process and hard roof disposal and analyzed the actual application effect. The results showed that the chamfered section fully mechanized caving process achieved efficient and safe mining of steeply inclined thick coal seams. It is hoped to provide reference and guidance for other mines.
