MGN132/316-DW type low seam electrical traction shearer;

Intrduces a equipment of low seam mining support-ZY3300/07/13D the low seam hydraulic support.

Through technical analysis on demolition mining engineering for hard thin coal beds in Fujian Province,this paper proposes that if the coal bed coefficient of hardness is different,the researched emphasis is accordingly different.

Mainly introduced the application of Solidworks software to hydraulic pressure support design in thin coal bed,the hydraulic pressure support which designed using Solidworks software in thin coal bed,had achieved the design goal and the request.

This paper analyses and experiment on the problem whether the near distance thin coal bed can be exploited by means of uphill low support synthesis mechanization extraction.

Regarding the extremely thin coal bed coal and the gas prominentpossibility analysis,in formerly practiced was a blank,therefore inthe production process knew and took the degree to be insufficient.
