巩义鑫 China Machinery Mining Knowledge Forum: mining filled with water to form a mining method to mine and gushing great influence, for example, when the Ministry of mining work surface aquifer, water break, when moisture karst and surface water bodies, you can not use Caving mining. Otherwise it will cause water inrush. If using fill mining method, deformed rocks of the many small, and mining is also little or no impact on the ground, the dewatering of the aquifer itself confined to the mining regions and directly adjacent to the area of ??hydrous rocks, but the cost is very high tunnel construction Therefore the choice of mining method must be considered because of the hydrogeological Ying. Due to mining activities, rock around the balance is broken, a lot of open pit excavated earth and rock to form a mound around the stope and earthen trenches, changing the terrain in the region, including stope cut side (across) the water layer, destruction of natural permeability and groundwater pathways. So that the top of the rock underground mining, drop, move, and destruction, collapse and cracks appeared in the ground. They and rural buildings and transportation equipment deformation and destruction. Deposits big tub drain will cause land subsidence, groundwater levels will Daifuku was reduced, and industrial and agricultural Production conflict. At the same time also make increasingly serious water pollution, wastewater discharge Furthermore mine will pollute the environment. These issues have a profound impact on the construction of the future development of the mining area. In the evaluation should be considered. Gongyi City Xinhua Machinery Factory is a leading manufacturer of slag machine, the production of slag machine, picking mining machine products sold abroad, small water conservancy project construction can be used to control the diesel-powered tire Pa mining machine tunnel construction equipment car, it has a hydraulic walking, digging acquisition, belt conveyors, clear bottom, and other functions. Deposits may be suitable for some upper-day mining tunnel Bo rake slag, the lower for underground mining. Tunnel construction machinery and mining under Either way, we must consider the geological conditions orebodies, economic comparison and demonstration program, select the correct mining methods. Spatial Characteristics ore deposit mining also affects the development plan, mining method, pumping mode transport, mining depth is determined to arrange the order of mining tunnels and mining, transportation roadway length and layout design. Gongyi City Xinhua Machinery Factory is a leading manufacturer of slag machine, the production of slag machine, picking mining machine products sold abroad, small water conservancy project construction can be used to control the diesel-powered tire Pa mining machine, which has Hydraulic walking, digging acquisition, belt conveyors, clear bottom, and other functions. Gongyi City Xinhua Machinery Factory is specialized in producing slag machine manufacturers, you are welcome to inquire. We must first determine the location of the sound source, they are likely to occur in these areas: 1, the noise from the hydraulic cylinder (1) hydraulic oil mixed with air or hydraulic cylinders in the air is not completely drained, cavitation under high pressure caused a large noise. Response options: At this point, the air must be promptly drained. (2) slag machine cylinder head or piston rod seal tight bend in the course of the campaign but also because of other fresh produce noise. Response options: At this point, need to be replaced or straightening rod seals. 2, the noise from the piston pump or motor (1) cavitation phenomenon is one of the main causes excessive pump noise. When the oil is mixed with air, easily formed in the high-pressure zone of cavitation, and in the form of pressure wave propagation, causing fluid oscillation, causing the system to generate cavitation noise. Tunnel construction equipment slag _ _ Mianyang tunnel mining machinery provided by Gongyi City Xinhua Machinery Factory. Gongyi City Xinhua Machinery Factory (www.gyxinhua.com) strong, credible, in Zhengzhou, Henan handling equipment industry has accumulated a large number of loyal customers.
