特厚煤层放顶煤开采技术与实践

针对黑岱沟煤矿6煤特厚煤层赋存地质条件,科学设备配套选型,采用低位放顶煤支架,并对后部运输机进行防滑操作技术改进,有效控制后部运输机串量。采用大采高割煤、多轮间隔放煤回采工艺,加强工作面现场管理,通过603综放工作面的成功回采,实现了矿井高产高效。

In view of the geological conditions of the extra thick coal seam of No.6 coal in Heidaigou Coal Mine,the scientific equipment is selected,the low top coal caving support is adopted,and the anti-skid operation technology of the rear conveyer is improved to effectively control the number of rear conveyer.The coal cutting technology with large mining height and multi-wheel interval mining technology is adopted to strengthen the field management of the working face.Through the successful mining of 603 fully mechanized top coal caving face,the high yield and high efficiency of the mine are realized.
