Problems solved by technology

[0003] When the traditional sealing products use polyurethane to seal the holes, the two kinds of polyurethane react and heat up. When they are put into the woven bag and sent into the hole, the leakage is serious, which will damage the operator's skin, eyes and other parts and pollute the environment. When the internal water is serious, especially the downwar

Embodiment Construction

[0049] The present invention will be further described below in conjunction with accompanying drawing:

[0050] Such as figure 1 As shown, the mine hole sealer described in the first embodiment includes a drainage casing 2 and a grouting pipe 3, the drainage casing 2 is arranged in the pre-sealing section of the gas drainage pipe 1, and the drainage The casing 2 is sleeved with an orifice pocket 4 near the orifice end, and a hole bottom pocket 5 is sleeved near the bottom end of the hole. The grouting pipe 3 passes through the orifice pocket 4 and the hole bottom pocket 5 and is fixed on the On the pumping casing 2, the end of the grouting pipe 3 is closed, and the grouting pipe 3 is provided with a one-way valve 6 on the position section in the hole bag 4 and the hole bottom bag 5, and the grouting pipe 3 is in the orifice. A burst valve 7 is arranged on the position section between the pouch 4 and the outside of the pouch 5 at the bottom of the hole.

Abstract

The invention discloses a mining hole packer and a hole packing method, and solves the hole packing problem of downward drilling holes and drilling holes filled with water. The mining hole packer comprises a drainage sleeve and a grouting pipe. The drainage sleeve is arranged at the hole pre-packing section of a gas drainage pipe. Pockets sleeve the two ends parts of the drainage sleeve respectively. The grouting pipe passes through the two pockets to be fixed on the drainage sleeve. The tail end of the grouting pipe is sealed. One-way valves are arranged at the position sections, in the pockets, of the grouting pipe. An explosion valve is arranged at the position section between the exteriors of the two pockets of the grouting pipe. The mining hole packer and the hole packing method can realize automatic hole packing, are convenient to operate, improve the drilling hole packing quality and the extraction effect, and besides, save manpower and material resources.

Description

technical field [0001] The invention relates to the field of sealing various drainage drilling holes in mines, in particular to a mine sealing device and a sealing method. Background technique [0002] Mine-used hole sealer, referred to as hole sealer, is mainly used for tight sealing of various drainage drilling holes in mines. The traditional sealing products are composed of polyurethane, woven bag, four-point iron pipe, four-point ball valve, etc. The sealing process is to put the two polyurethanes mixed at 1:1 into the woven bag on site, and use the four-point iron pipe Send it into the designated position in the hole and the position near the orifice, and use the four-point iron pipe into the hole as the grouting pipe and the grouting pipe. After the polyurethane fully reacts and expands, start grouting, and control the flow and flow through the four-point ball valve. Cut off and keep slurry. [0003] When the traditional sealing products use polyurethane to seal the ...
