Description

Technical Field

[0001] This application relates to the field of mining technology, and in particular to a device for fixing a false bottom in a downward triangular region to improve stability. Background Technology

[0002] In related technologies, the downward-facing horizontal layered filling mining method refers to top-down layered mining, constructing a false roof for the next layer during the mining of the previous layer, and mining the next layer under the protection of the false roof. This method changes the mining and filling sequence from top to bottom and constructs a solid artificial roof for each layer. When mining inclined or gently inclined ore bodies, the ore at the bottom corner of the hanging wall in the stope forms a triangular area. Due to the dip of the ore body, when the false bottom of the triangular area is exposed in the next layer, the false bottom is unstable and prone to cracking and delamination. Utility Model Content

[0003] To address or partially address the problems existing in related technologies, this application provides a downward-facing triangular area false bottom stability fixing device. This device can add inclined hook bars in the triangular area to connect the false bottom steel bars in the triangular area with the hanging pile through bars, ensuring the stability of the false bottom in the triangular area and improving the safety of mining.

[0004] This application provides a device for fixing the stability of a downward triangular area false bottom, including a diagonal hook bar, a vertical hook bar, a false bottom hanging pile, and a false bottom reinforcing bar. An inverted wedge-shaped false bottom hanging pile with a ring is provided at the waistline of the mine, and false bottom reinforcing bars are laid at the bottom of the mine. The vertical hook bar connects the false bottom hanging pile and the false bottom reinforcing bar, and a triangular area is formed by setting the diagonal hook bar. The diagonal hook bar and the vertical hook bar form an angle of 30-45 degrees.

[0005] Optionally, in some embodiments, the false bottom stake forms an angle of 15-20 degrees with the mine waistline.

[0006] The technical solution provided in this application may include the following beneficial effects:

[0007] This application provides a device for fixing the stability of a false bottom in a downward triangular area. This device can add inclined hook bars in the triangular area to connect the false bottom steel bars in the triangular area with the hanging pile through bars, thereby ensuring the stability of the false bottom in the triangular area and improving the safety of mining.

The hanging piles are 150cm high, spaced 100cm apart, with 20cm of the wedge and anchor ring exposed. False bottom reinforcing bars 5 are laid at the bottom of the stope. The vertical hook bar 2 connects the false bottom hanging pile 3 and the false bottom reinforcing bar 5. The diagonal hook bar 1 forms a triangular area. The vertical hook bar 2 is 150cm long and made of Φ14mm threaded steel with round hooks at both ends. It connects the anchor ring of the false bottom hanging pile 3 and the false bottom reinforcing bar 5 through a through-bar connection. The diagonal hook bar 1 and the vertical hook bar 2 form an angle of 30-45 degrees, effectively improving the stability of the false bottom in the triangular area and preventing collapse. The false bottom hanging pile 3 forms an angle of 15-20 degrees with the waistline 4 of the stope, improving the stability of the false bottom hanging pile 3.
