hydraulic mine
2.Chengdu Longquan Reixing Engineering Materials Plant Set product development, manufacturing and marketing its products and services into one, through the introduction, absorption, development and production of innovative self-drilling bolt grouting hollow products and exclusive ancillary machinery widely used in underground engineering (Traffic Tunnel, hydraulic tunnels, mine roadway Road and the various uses of Anchorage Support) geotechnical engineering (slope, dike rocks, the deep excavation Anchorage Support) repair Reinforcement Project (tunnels, dikes, dams, housing construction).
5.TECHNOLOGY FOR MINE OF HIGH EFFCIENCY ON SAFETY IN THE SINGLE HYDRAULIC PROP CANNON COAL FACE
6.This paper bring forward a new design method that use virtual prototyping technology to design single hydraulic props, which is based these condition characteristic: people now broadly adhibit single hydraulic props to support in general mining and in advanced general mining work face, and synthesize condition under coal mine, single hydraulic prop update quickly, ect.
7.This essay introduces the working principle of a new sort of equipment, Model YZI-450 hydraulic pressure rectifier, which can be used to restoring the I-steel beam and post in coal mine, and completes a detailed mechanistic calculation, and draws a ordinary conclusion on restoring the being out of shape hardly.
10.Products are: super high pressure electric, pneumatic, manual oil pump; pre-stress Jack for the use of coal mine and construction; steel bar and cable scissor; all kinds of bolt for safety supporting and bolting (KM19 and KM22 bolt have all got the certificate of “MA” in China.); cable anchor and bolt test stand; hydraulic nut scissor and etc.
