大幅度不等长调斜技术在综采工作面的应用

Application of Large-scale and Variable-length Slope Adjustment Technology on Fully-mechanized Working Face

为了最大限度地回收煤炭资源,工作面需进行大幅度调斜。介绍了车集煤矿2607综采工作面在收尾过程中,成功应用虚中心调斜技术,在工作面斜长增加过程中采取相关技术措施,实现工作面大幅度不等长调斜收尾,提高了煤炭采出率,为不规则工作面调斜开采提供了经验。

In order to recover coal resource extremely,the working face must be made a slope-adjustment by a large margin.The virtual-center slope-adjustment technology was adopted in final work on 2607 working face in Juji Coal Mine.Relevant technics measures were used when oblique length of working face increases.The application of above measures accomplished large-scale and variable length slope-adjustment of working face,and increased coal recovery ratio,it also can provide practical experience for similar mining activities.
