特厚较软煤层开采设备的改进与应用

Improvement and Application of Mining Equipment for Extra Thick Soft Coal Seam

分析了特厚较软煤层特殊的条件现场,并考察了现有的采煤工艺和设备,基于分析考察的结果,指出了现有特厚较软煤层开采设备在液压支架、大功率刮板输送机启动方式和截割采煤机存在的问题及相应的优化与改进措施。优化后的工作面设备能够完全适应特厚较软煤层独特的条件。

This paper analyzes the special conditions of the extra thick and soft coal seam, and inspects the existing mining technology and equipment. Based on the results of the analysis and inspection, it points out that the existing mining equipment of the extra thick and soft coal seam is in the hydraulic support. The problems existing in the starting mode and cutting shearer of high power scraper conveyer and the corresponding optimization and improvement measures are put forward. The optimized working face equipment can fully adapt to the unique conditions of the thick and soft coal seams.
