大采高综采工作面重装备单通道搬家技术

Longwall face with big mining height:the use of single tunnel for heavy equipment move

针对斜沟煤矿8号煤层综采工作面采高大、装备重,搬迁困难的问题,分析了现有搬家技术的优缺点,提出了单通道搬家技术,介绍了大采高综采工作面重装备单通道回撤系统、大采高综采工作面重装备调车硐室安装系统,以及实施效果和应用前景。

To solve the tough problem of heavy type longwall face equipment move in # 8 coal seam with big cutting height in Xiegou Coal Mine, an analysis is done on the advantages and disadvantages of the presently available longwall face moving technology. On the basis of this, a long wall face moving technology employing a single tunnel is proposed. This paper introduces the heavy face equipment retrieval system and underground heavy type longwall face equipment dispatching chamber installation system for use in longwall faces with big mining heights. The paper also provides an account about the application results of this technology and its application prospects.
