Description

Technical Field

[0001] The utility model relates to the technical field of coal seam mining, in particular to a guide rod type filling support. Background Art

[0002] With economic development and improved living standards, people's demands for the environment are becoming increasingly stringent. As proven mineral resources continue to deplete and mining progresses deeper, traditional mining methods often leave large goafs after mining. Over time, these can easily lead to geological disasters such as surface collapse, mountain cracking, or collapse. Furthermore, traditional mining methods leave behind a large number of pillars that cannot be recovered, resulting in a waste of resources. However, backfill mining addresses these issues. After mining, backfill mining uses inexpensive materials to fill the goaf, preventing ground collapse. Backfill mining eliminates the need for pillars, thereby improving ore recovery, protecting mineral resources, and achieving excellent economic benefits. Utility Model Content

[0003] In order to solve the problems existing in the prior art, realize effective isolation and support of the filling area, and achieve the recycling of mineral resources, the utility model provides a guide rod type filling support, which is a hydraulic support used in conjunction with the filling process.

A filling baffle 5 that can be extended and retracted up and down is also provided at the rear of the base 1. The lower part of the filling baffle 5 is connected to the rear end of the base 1 through a connecting rod 6. The connecting rod 6 here can be a horizontally arranged jack that can control the support position of the filling baffle 5. Since the guide device 4 in the utility model adopts a vertical setting structure, that is, a vertical guide rod is used as a stabilizing mechanism, the structure is compact, the length of the top beam is small, the support strength is large, and it is easy to realize underground transportation.

[0028] like Figure 1 As shown, preferably, the rear plane of the filling baffle 5 is arranged parallel to the rear end of the base 1, and the filling baffle 5 includes a supporting baffle 51 and a telescopic baffle 52. The telescopic baffle 52 is installed on the supporting baffle 51 through a lifting device 53, and is hinged to the base 1 through a connecting rod 6 at the bottom end of the supporting baffle 51, which makes it easier for the bottom end of the supporting baffle 51 to contact a larger area of ​​the tunnel floor; the lifting device 53 here can be a vertically arranged jack structure, the upper end of which is connected to the telescopic baffle 52. When the lifting device 53 is controlled to rise and fall, the telescopic baffle 52 moves up and down along the supporting baffle 51.

[0029] As a further preferred embodiment of the present invention, the support baffle 51 in the present invention has a chamber in which the telescopic baffle 52 can be placed. The upper end of the support baffle 51 is open, and the telescopic baffle 52 is placed into the chamber from the upper end opening of the support baffle 51.
