Description
Technical field
The utility model is related to a kind of support apparatus field of large-inclination-angle coal bed mining working face, and in particular to one kind is used for
The support group of coal mining.
Background technology
Coal seam is respectively divided into slow tiltedly (0 °~25 °) by inclination angle, tilts (25 °~45 °) and anxious oblique (45 °~90 °) by China
Three classes.It is large-inclination-angle coal bed not provide definite definition also so far, but the natural repose angle that is slided according to caved gangue and
The general applicable angle of hydraulic support maximum, it is believed that large-inclination-angle coal bed to be primarily referred to as this class coal seam, inclination angle that inclination angle is more than 35 °
The upper limit can be 55 ° or 60 °.It is large-inclination-angle coal bed that main producing coal country of the world has that reserves differ.In China's high inclination-angle
The storage capacity in coal seam constitutes about the 14.05% of coal gross storage capacity, and these coal seams are mainly distributed on Sichuan of China, Xinjiang, wide
East, Fujian, Gansu, the Inner Mongol and northeast etc. save (area), and large-inclination-angle coal bed annual production constitutes about the 8% of national coal total output
~10%, but occupy very big ratio in the large-inclination-angle coal bed yield of some provinces (area), as in Sichuan Province 40%~50%
Coal production comes from large-inclination-angle coal bed.Accordingly, with respect to the mine pressure rule in mining steeply dipping coal seam method and recovery process
Development of the research of rule and roof and floor movement law to China coal industry still has particularly significant effect.
The demand of current coal in China is increasing, and corresponding coal mining is also more next to grow.Big inclined seam reserves are accounted for
The 8% of coal in China gross reserves, particularly in southwestern section, 80% mining area preservation has big inclined seam.For a long time, such
The exploitation in coal seam is extremely difficult, and efficiency is low, cost is high, and safe pressure is very big.Traditionally the supporting to ultra-thin coal seam is typically used
Two kinds of forms of mine timber supporting or individual prop supporting, but both support patterns are all present that labor intensity is big, supporting intensity is low,
Safe condition is poor, the low defect of efficiency.
In recent years, with the development of coal-mining technique, fully mechanized mining and top grade are also used in the deep inclined thin coal seam of some mines
It is general to adopt technology.But due to coal seam feature, in the traction of coal-winning machine, the installation of support, regulation, propulsion aspect are very difficult, make
High into cost of winning, labor intensity is big.Therefore for the exploitation of deep inclined thin coal seam, it is badly in need of a kind of new support equipment to solve
Certainly problems faced.
