摘要
红菱煤矿701工作面地质构造复杂,中部形成110°拐角的扇形区段。对此,红菱煤矿实施了综采扇形开采技术。介绍了工作面地质概况和装备情况,阐述了综采工作面扇形开采技术方案和工艺。
Due to complicated geological conditions in the #701 face in Hongling Coal Mine,a fan-shaped curving section of 110°is encountered in the middle part of the face.So fan-shaped longwall mining method is adopted in this mine.In this paper,a general description is given on the geological conditions of the mine and the equipment used in the operation while focus in laid upon the technical scheme and execution of the fan-shaped longwall mining.
