Problems solved by technology

Human beings need energy to dig underground mineral deposits. For a long time, most of the materials used in the mining process are wood and Portland cement materials. The basic national policy of deforestation is repeatedly ordered; on the other hand, the shortcomings of wood and Portland cement materials are obvious to all. The former is easy to corrode after being exposed to moisture and has a low safety factor, while the latter has a large specific gravity, is difficult to construct, and is easy to crack

Abstract

This invention relates to a shaft engineering material used for pitprop and crosstie, mostly includes bamboo reinforcement skeleton. According to weight the bamboo reinforcement skeleton includes follow components: magnesia 10 to 80 shares, magnesium chloride 5 to 30, wood flour 10 to 50, semi-hydrated gypsum 5 to 20, plastic fibre 1 to 5, ferrous sulfate 1 to 10, oxalic acid 1 to 3, water 30 to 60 shares. This invention also relates to the preparation method. This invention can effectively avoide insufficiency of traditional stuff such as perishable, flammability and easy exploding, also possess unique merits such as ageing resistance corrosion prevention, fireproofing, waterproof and be able to saw and cut and so on in the moist roadway environment.

Description

technical field [0001] The invention relates to an inorganic mine support material, in particular to a mine engineering material for pit wood sleepers and a preparation method thereof. Background technique [0002] China is a large natural country rich in underground mineral deposits. Since the mining of underground mineral deposits, wood and cement products have been used as underground roadway support and track bedding. In recent years, metal products have also been used as supports, while wood is perishable, flammable, explosive, and has a short pressure-bearing time; cement products have a large proportion, are difficult to construct, and are brittle and easy to crack, making them difficult to replace. The cost of metalwork is high and it is inconvenient to hang cables. [0003] Throughout the history of the world, energy has been a long-term need of mankind. Human beings need energy to dig underground mineral deposits. For a long time, most of the materials used in th...
