Background technique

With the rapid development of fully mechanized mining technology, the requirements for the technical level of existing excavation equipment are getting higher and higher, and the contradictions of unbalanced mining ratio and tight production continuity have become increasingly prominent. The main reason for the low excavation efficiency is the unbalanced excavation and support. The coal cutting time in the working face usually accounts for 17% to 34%, while the support time accounts for 50% to 67%. The problem of "support such as excavation" greatly restricts In order to improve the footage speed, at the same time, in the process of anchoring, a bolter needs to be matched with 2-3 operators, and many problems of anchoring operators are becoming more and more prominent. Therefore, it is necessary to explore the production technology and equipment for parallel operations of excavation, support, and transportation, in order to fundamentally solve the problem and achieve efficient and safe rapid excavation, which is also in line with the coal mine's policy of reducing staff and increasing efficiency.

Anchor cable support is an important support method. The anchor cable support technology has been widely used in coal mines in my country.
