运输顺槽转角、回风顺槽一次性延面研究

Studies on conveying airway corner and return airway extending face at combined mechanization equipment mining face

对铁煤集团大隆矿W1902综放工作面在运输顺槽转角开采及综放工作面回风顺槽一次性延面进行了分析。通过对矩形回采工作面和一次性延面两种不同方案的比较,为提高煤炭回收率提出了解决问题的优化方案,破除了以往综放工作面运输顺槽不转角的难题,为不规则工作面采用新工艺开采、新工艺设计提供了借鉴经验。

Full - mechanized caving faces W902 of the Dalong Mine about return airway comer mining and the return airway side of the disposable extending surface were analyzed; Optimized plan was proposed to solve the question to enhance the coal returns - ratio. The plan eradicated the former difficult problem about the return airway of full - mechanized caving faces. The results provided the model experience for new craft mining and new technological design for the irregular working surface.
