[0018] like Figure 1As shown in the figure, a dedicated end hydraulic support for gob-side tunnel retaining with an auxiliary gangue-clearing device on its base comprises an end hydraulic support 3 and an auxiliary gangue-clearing device. The auxiliary gangue-clearing device comprises a cleaning shovel 1 and multiple reciprocating drive mechanisms 2. The multiple reciprocating drive mechanisms 2 are mounted on the base of the dedicated end hydraulic support 3 for gob-side tunnel retaining. The cleaning shovel 1 is hinged to the drive ends of the multiple reciprocating drive mechanisms 2 and is arranged vertically and diagonally.

[0019] In response to the problems of low efficiency and safety risks in the manual cleaning of coal gangue in the hanging formwork area of the goaf-retaining tunnel in the current shielded end hydraulic support, the utility model provides a special end support for goaf-retaining tunnels with an auxiliary gangue cleaning device on the base of the end support, which can timely and actively clean the coal gangue to the middle of the tunnel, avoid construction time conflicts in this area, improve the construction efficiency of goaf-retaining tunnels, and enhance the safety guarantee capability of goaf-retaining tunnels.

[0020] The utility model discloses a special hydraulic support for the end of a goaf-side tunnel with an auxiliary gangue cleaning device on the base. The component used for cleaning is the auxiliary gangue cleaning device, which consists of a cleaning shovel 1 and a reciprocating drive mechanism 2. The middle and lower parts of both sides of the cleaning shovel 1 are connected to the driving end of the reciprocating drive mechanism 2, and the reciprocating drive mechanism 2 is installed on the base of the end support 3. Figure 2 Under normal circumstances, the bases of the cleaning shovel 1 and the end bracket 3 are tilted both horizontally and vertically. The movement of the end bracket 3 drives the cleaning shovel 1, shoveling the gangue to the center of the tunnel. Under special circumstances, the reciprocating drive mechanism 2 is controlled to extend and retract, thereby controlling the movement of the cleaning shovel 1 to further collect the gangue. The cleaning shovel 1 has a width of 1750mm and a height of 200mm-1000mm. The specific size can be selected based on actual underground working conditions and is not strictly limited.

[0021] The working state of the shielded end hydraulic support is that the end support along the goaf is supported in the dynamic pressure tunnel, and the special end support along the goaf with an auxiliary gangue cleaning device on the end support base of the utility model can timely and actively clean the coal gangue to the middle of the tunnel through the auxiliary gangue cleaning device, avoiding the construction time conflict in this area, improving the construction efficiency of the goaf and enhancing the safety guarantee capability of the goaf.

[0022] During the mining process of the working face, a special end hydraulic support with an auxiliary gangue cleaning device on the base is used to clean the gangue along the goaf. After the end support of the comprehensive mining working face is advanced by one step, the end hydraulic support 3 drives the auxiliary gangue cleaning device to move forward at the same time. The movement of the end hydraulic support pulls the gangue cleaning device to shovel the gangue to the middle of the goaf. In special circumstances, the extension degree of the reciprocating drive mechanism is controlled to control the movement of the cleaning shovel 1 to ensure that the cleaning shovel 1 acts on the bottom plate of the goaf, and the gangue is cleaned to the middle of the goaf in a timely and proactive manner, avoiding the construction time conflict in this area, improving the construction efficiency of the goaf and improving the safety guarantee capability of the goaf. After the gangue cleaning is completed, the end support can continue to advance, and the reciprocating cycle operation is repeated.
