Description

Technical Field

[0001] This invention belongs to the field of coal pillar-free mining technology along the goaf, specifically involving the split roof beam anchor end support. Background Technology

[0002] With the increasing depth of coal mining and the promotion of efficient mining technologies, roadway retention mining technology has become an important development direction in the mining industry due to its ability to effectively improve resource recovery rates and reduce roadway excavation costs. During roadway retention mining, the end area, as a critical connection between the roadway and the working face, bears the strong dynamic pressure impact from the working face's retreat mining. Simultaneously, it needs to accommodate the installation and maintenance space of the anchor bolt (cable) support system. Its support effect directly determines the stability and safety of the roadway retention. Therefore, developing support equipment suitable for the complex working conditions at the end of roadway retention has become one of the core requirements for ensuring the efficient advancement of roadway retention mining.

[0003] Currently, the main support equipment used in the field of end-face support in tunnels is the integrated roof beam support. However, the integrated design of the roof beam structure of this type of support has revealed obvious defects in practical applications, making it difficult to adapt to the complex requirements of end-face support. On the one hand, the integrated roof beam cannot be flexibly adjusted according to the specific position of the already installed anchor bolts (cables). During the installation and support process, it is very easy to directly interfere with the already installed anchor bolts (cables), causing damage to the anchor bolts (cables), resulting in a decrease in the strength of the surrounding rock support and significantly reducing the reliability of the surrounding rock support. On the other hand, in the anchor bolt (cable) installation operation, anchor bolts (cables) can generally only be installed before or after the support frame. If installation is chosen before the support frame, the roof beam is prone to squeezing and damaging the already installed anchor bolts (cables), requiring subsequent reinstallation, which increases the economic cost of materials and labor and delays the progress of the working face. If installation is chosen after the support frame, the roof is prone to a "netting" phenomenon during support, which damages the integrity of the roof rock layer, creating a potential risk of roof instability and seriously threatening production safety.

[0004] To address the shortcomings of existing technologies, there is an urgent need to develop a new type of end-face support adapted to the working conditions of roadway ends. This support must be able to flexibly avoid existing anchor bolts (cables) to effectively protect the integrity of the existing roof support structure. At the same time, it needs to overcome the limitations of traditional supports that can only install anchor bolts (cables) before or after the support, and realize the installation of anchor bolts (cables) between supports. This would fundamentally avoid the risk of compression damage before the support and the risk of "netting" after the support, ensuring the safety of roof support, and simultaneously improving the efficiency of roadway construction, thus providing equipment support for roadway mining technology.
