Abstract: In view of the problem that the advanced support technology of the fully mechanized mining face of Tashan Coal Mine of Tongmei Group has repeated roofing, it is easy to cause the roof to be broken, the number of operators is large, and the labor intensity is large. Based on the roof of the fully mechanized mining face of the middle thick seam of Tashan Coal Mine of Tongmei Group The law, combined with theoretical calculation design, developed a new vehicle-mounted advanced no-repetition support process equipment and completed industrial tests. The test shows that the use of the roadway without repeated support equipment effectively avoids the phenomenon of repeated support of the existing lead bracket during the support process, and the number of support workers is reduced by 70%, and the mechanization of the advance support is realized, which proves the dehumanization of the process. The advantages and advancement of the operation provide an effective way for the development of new intelligent mines with the characteristics of “intrinsically safe mines, high-efficiency mines and clean mines”.
