Embodiment Construction

[0016] A hole sealing material for a mining hole sealer, which is composed of the following parts by weight: calcium hydroxide 0.5-0.8, sodium chloride 0.5-1.5, sodium thiosulfate 1.0-2.5, pulling powder BX 0.1-0.4, calcium silicate 1~5, water reducer JN 0.2~0.4, ammonium chloride 0.3~0.7, aluminum hydroxide 0.001~0.006, calcium chlorate 0.001~0.006, iron powder 80~90, calcium carbonate 1.2~1.5, magnesium hydroxide 0.05~0.20.

[0017] Further, the method for using the hole sealing material of the mining hole sealing device for hole sealing is as follows: 1. Install the hole sealing device: clean the borehole, and cover the bag with the end of the pressure head on the first hole of the required sealing length. On one suction pipe, the grouting pipe is fixed on the suction pipe with scotch tape, and the 1cm at both ends of the pouch is first fixed with cable ties, then tightened with thin wire, and covered with scotch tape successively; Put the pouch at the other end on the las...

Abstract

The invention discloses a mine use hole packer hole packing material which is composed of the following components by weight: 0.5-0.8 part of calcium hydroxide, 0.5-1.5 parts of sodium chloride, 1-2.5 parts of sodium thiosulfate, 0.1-0.4 part of Nekal BX, 1-5 parts of calcium silicate, 0.2-0.4 part of water reducing agent JN, 00.3-0.7 parts of ammonium chloride, 0.001-0.006 part of aluminum hydroxide, 0.001-0.006 part of calcium chlorate, 80-90 parts of iron powder, 1.2-1.5 parts of calcium carbonate and 0.05 to 0.20 part of magnesium hydrate. The mine use hole packer hole packing material realizes the rapid expansion solidification, the tine is improved from 30 minutes in the prior art to 10 minutes, gas drainage-suction borehole sealing tightness is good, water exploration can be quickly realized by water exploration borehole and sealing, in pressure measuring borehole and sealing, pressure measuring can be realized in 24h, operation is simple, use is convenient, the labor intensity is reduced, work efficiency is improved, and the mine use hole packer hole packing material is suitable for hole sealing of various borehole under coal mine wells.

Description

technical field [0001] The invention relates to a hole sealing material, in particular to a hole sealing material for a mine hole sealing device. Background technique [0002] With the deepening of coal mining year by year, the gas content in coal seams has also increased, and the proportion of high gas mines and coal and gas outburst mines has increased. Starting from safe production, my country has issued a sixteen-character policy for coal mine gas management, which is "reliable ventilation, up to standard drainage, effective monitoring, and proper management". As far as the core content of "drainage meets the standard" is concerned, it is very difficult to meet this requirement in hard-to-drain coal seams. Even in coal and gas outburst mines, some mines have to be closed for this reason. Gas has become a serious restrictive factor in my country's coal production at present and even in the future, and is one of the main bottlenecks of coal development. To break through t...
