Gongyi Xin Hua Knowledge Forum mining machinery, mining development of water resources. Mine development required to supply water hydraulic, general direct use of surface water. When no local water table can also be drinks pit row into the ground structure. Treated as a source of water supply, but in any case, be sure to meet the water quality standards, the living water to meet drinking water standards, water pit with a minimum of equipment erosion as a benchmark. Identify the necessary and sufficient conditions for deposits after water, the need for pre-mine water inflow side, which is an important indicator to determine the extent of geologic deposits in hydrology have a great impact on the complexity of the technical and economic evaluation of deposits, is to determine the drainage equipment and production an important basis for competence. Conduct pre Chung Chau basin. Must follow the three original to: identify mine hydrogeological conditions. Calculation parameters representative;. The right choice mathematical model of 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 diesel power control tire Pa mining machine, which has a hydraulic walking, digging acquisition, belt conveyors, clear bottom, and other functions.巩义鑫 China Machinery Mining Knowledge Forum COLLECTION: spatial characteristics of the ore body means the ore body in three-dimensional space has features, such as ore body shape, occurrence, width, thickness, depth of burial and so on. These factors inherent in ore deposits in ways largely determine the development and utilization. Depth of burial is decided Deposits opencast or underground mining. In general the cost of open-pit mining is lower than underground mining. But this is not always the case, It depends on the specific conditions of occurrence deposits. Deposits although some shallow due to a large amount of stripping rock, its cost is not economical than underground mining, have mined using underground. Of course, some deposits in buried deep underground mining would only Gongyi City Xinhua Machinery Factory is a leading manufacturer of slag machine, the production of slag machine, picking mining machine products sold abroad, the choice of small water conservancy construction diesel-powered control tire Pa mining machine, which has a hydraulic walking, digging acquisition, belt conveyors, clear bottom, and other functions. Yan'an Yellow River diversion project to start building Yanchang Petroleum Corporation Yan'an Yellow River diversion project at the Royal Town Yanchuan county extension of water Qucun construction. Yanchang Petroleum Corporation Yan'an Yellow River diversion project from the Royal Town Yanchuan county extension of water drainage water, and along the way by Yanchuan county Yanchuan, pagoda County District 8 towns to Yan'an with water hydraulic mining machine, a total length of 133 water pipeline .57 kilometer hydraulic excavators, along a total of eight pumping stations, through the tunnel section 7, a total investment of 1.026 billion yuan, total construction period of 5 years. After the project is completed, you can every day to Yan'an city water supply 110,000 cubic meters of hydraulic power rake can be made to Yanchuan, extended length son, Yong Ping, such as urban water supply 40,000 cubic meters per day. The same period, Yan'an City Hongzhuang reservoir water supply line project started. The starting point for the Red Village Reservoir Engineering, Yan'an University Graduate front end to the original aqueduct. A total length of 8.57 km pipeline, the total investment 39,876,400 yuan, expected to be completed by the end of June 2009. China is the production of slag 巩义鑫 professional manufacturers willing to sacrifice the power of livelihood projects to this end! 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.
