Guyuan County diversion project, water is the source of life, is the material basis for human survival and development. However, due to drought and water shortage, is located in the arid and semi-arid mountainous southern Ningxia region's economic and social development are severely constrained in Guyuan County, but also hindered the survival and quality of life improved. Along with social progress and development day by day, water scarcity and more prominent in Guyuan County, the demand for water more urgent. According to statistics, 10 years later, Guyuan county's population will increase to 15.6 million, total industrial output value of 10 billion four-wheel hydraulic slag machine, the annual water demand of 23.3 million cubic meters, according to the current water supply Guyuan County inventory and annual water demand calculations, in another 10 years, 20 years, the county will be a serious water shortage. How to seize the western development opportunities in the development process, speedy completion of the county urbanization, water, and again become an unavoidable topic. East hillside construction diversion project is the only way to solve this problem. ? 巩义鑫 China is producing slag professional manufacturers willing to sacrifice power livelihood projects to this end!

Mining companies are mining ore or mineral raw materials production units, 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 deeply buried ore deposit, you 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, some economically worthwhile. But Not really, if the open-pit mining of high-quality hydraulic brake from large pots Cinder machine, 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. Four-wheel hydraulic slag machine, crawler Cinder machine (certified), Panzhihua hydraulic slag machine provided by Gongyi City Xinhua Machinery Factory. Gongyi City Xinhua Machinery Factory (www.gyxinhua.com) is a leader in Zhengzhou, handling equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Xinhua leader in mechanical staff warmly welcome all inquiries negotiations to create a better future, Xinhua machinery.
