Grilled scraper mining machine | Xinhua machinery (certified) | Ezhou scraper provided by Gongyi City Xinhua Machinery Factory. Gongyi City Xinhua Machinery Factory (www.gyxinhua.com) is specialized in the "Cinder machines, construction machinery, mining machinery, chemical machinery" of the enterprise, the company of "honesty, hard service" concept, to provide you with the most quality products and services. Welcome to inquire! Contact: Mr. Wang. Transfer is based on China's "Southern Water, less water north" This uneven distribution of water resources features proposed inter-basin water transfer project, sub-west line, east and center line, the Yangtze River water transferred from the northwest, north China . West line from the upper reaches of the Yellow River upper reaches of the Yangtze River water transferred to complement economic northwest dryland scraper machine configuration, the largest of about 20 billion cubic meters of water is adjustable. Tap water in east Jiangsu Jiangdu Sanjiangying scraper repair water mains along the Beijing-Hangzhou Grand Canal grading for water to inverted siphon across the Yellow River, the water line length of 2089 km, average 19.15 billion cubic meters of water pumped river. Han River Diversion Project water to start, after water from the Yangtze River, Hanjiang Danjiangkou Reservoir Engineering and heightened by the late scale were combined, and the diversion point for Taocha Qingquangou two Water Diversion Reservoir. ? 巩义鑫 China is producing slag professional manufacturers willing to sacrifice power livelihood projects to this end!巩义鑫 China Machinery Mining Knowledge Forum: Select mining methods. Mining companies are mining ore or mineral raw materials production units scraper, generally including the management of one or several open pit. Pit mine and production needs and to ensure a variety of auxiliary plant. Mined underground mining can be divided into day and fill mining. Deposits choose a pit (hole) mining or mom mining, mine should be based on the terrain to look, deposit geology and economic conditions exist Bin determined. If the deposits in the fill surface or shallow buried. It is suitable for open-pit mining. If the deposits in deeply buried scraper Grilled mining machine, can only adopt a pit, but some deposits in only to see both front and burying mining, you can pit mining. Generally fill mining pit mining costs are lower than some of the economic Some on cost-effective, but not necessarily, if the brake from open-pit mining large pots, from mining costs. It is necessary to consider the use of pit mining, and some may be part of the implementation of the female deposits in mining. Another pit mining practice. So for a deposit in the manner in which mining, geological conditions and topography from economic and other aspects were analyzed and compared in order to determine.
