斜井快速揭穿突出厚煤层防突技术

Deviated Well Quickly Expose Outburst Prevention Technique of Thick Coal Seam

通过分析煤矿缓倾斜突出煤层传统揭煤方法存在的缺点入手,提出"五步揭煤法"快速揭开缓倾斜突出煤层。该方法分五步实施预测,并根据预测结果采取相应防突措施,不仅减少了钻孔工程量和长钻孔施工困难,而且提高了揭煤速度,缩短了揭煤时间,降低了揭煤成本。

Through the analysis of coal mine slowly inclined coal seams the disadvantages of traditional method of uncovering coal, this paper put forward the ＂method of five step uncovering coal＂ quickly unravel slowly inclined coal seams.The method includes five steps in carrying out prediction and outburst prevention measures should be taken according to the forecast results, not only reduce the drilling quantity and long drilling construction difficulties, and improve the speed of uncovering coal, shortens the time of uncovering coal and reducing the costs of uncovering coal.
