Description

Technical Field

[0001] This utility model relates to the field of working face deformation detection technology, and in particular to a device for detecting the horizontal deformation of the filling body in a continuous mining and filling working face. Background Technology

[0002] Continuous backfilling is a green mining technology suitable for extra-thick coal seams. It achieves simultaneous mining and backfilling through layered mining, significantly improving resource utilization and mining efficiency. Backfilling should be carried out promptly after mining to reduce roof pressure and deformation. The number of mining and backfilling roadways in each group and the sequence of connections within each group should be adjusted according to the actual mining-backfilling connection and reserve occurrence. The spatial distance between the next mining roadway and the previous one should be no less than the width of three vegetable roadways to avoid stress superposition between mining roadways. During mining, both sides of the roadway should be solid coal or backfill material solidified to sufficient strength to ensure safety. Backfilling should be carried out as soon as possible after mining is completed to reduce the impact of mining on the surface.

[0003] The stability of the backfill body in a continuous mining and backfilling working face is closely related to the production safety of the working face and the subsidence of the corresponding surface structures. The horizontal deformation of the backfill body under long-term mining pressure can be used as an important indicator of the stability of the backfill body.

[0004] Currently, the main content of mine pressure monitoring in continuous mining and filling faces is monitoring of roof and floor rock movement and roof pressure, but there is no monitoring of the stability of the filling body. Summary of the Invention

[0005] Therefore, the purpose of this utility model is to provide a device for detecting the horizontal deformation of the filling body in a continuous mining and filling working face, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the following technical solution is adopted:

[0007] A device for detecting horizontal deformation of the filling body in a continuous mining and filling face includes a straight, elongated hole horizontally opened on one side wall of the filling body;

[0008] The elongated hole is perpendicular to the side wall. The inner end of the elongated hole is fixedly connected to one end of a steel wire rope. The other end of the steel wire rope is connected to a top plate separation device installed on the outside of the elongated hole. The top plate separation device is fixedly connected to the filling body. The top plate separation device is also connected to one end of a steel wire rope. The other end of the steel wire rope is fixedly connected to the side wall of the filling body where the elongated hole is opened.

[0009] As a further improvement to the horizontal deformation detection device of the filling body in the continuous mining and filling working face, wire rope one and wire rope two are located on the same horizontal plane.

[0010] As a further improvement to the horizontal deformation detection device of the filling body in the continuous mining and filling working face, the roof separation instrument adopts a digital display roof separation instrument.

[0011] As a further improvement to the horizontal deformation detection device of the filling body in the continuous mining and filling working face, the ends of wire rope one and wire rope two are fixed to the filling body by connecting hooks. Wire rope one and wire rope two are wrapped with a transparent rubber layer to prevent them from rusting, corroding and breaking.

[0012] As a further improvement to the horizontal deformation detection device of the filling body in the continuous mining and filling working face, wire rope one and wire rope two are set vertically.

[0013] The beneficial effects of this utility model are:

[0014] This device for detecting the horizontal deformation of the filling body in a continuous mining and filling face detects the deformation of the filling body in two perpendicular directions on a horizontal plane. It is easy to operate, safe and reliable, and provides accurate results. It solves the problem of detecting the stability of the filling body in a continuous filling face and can be used repeatedly.
