Explosion slag machine prices, Crawler Pa mining machine (certified), flameproof slag machine 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. Qin Gansu big lead "big Qin cited" through the water diversion project is completed the construction of the most difficult water diversion project ── lead up to the main canal 86.95km big Qin in June 26, 1994 all through, and in that year October smoothly through the water. After the completion of this large-scale gravity irrigation project 50 Flameproof Cinder machine, water 440 million annually m3, irrigation 57000 hm2 wilderness, so inaccessible Qinwangchuan ... Key words: water diversion project lead Large gravity irrigation project in the Hexi Corridor of Gansu Province Qin grain production base Qinwangchuan drinking water main canal construction difficulty 巩义鑫 China is producing slag professional manufacturers willing to sacrifice power livelihood projects to this end! Gongyi Xin Hua Machinery Mining Knowledge Forum: mining filled with water to form a mining method for mining and gushing great influence, for example, when the Ministry of mining work surface aquifer, water breaking, water and surface water in karst coal mine explosion when Cinder machine you can not use caving mining method. Otherwise it will cause water inrush. If using fill mining method, deformed rocks of the many small, and mining have little or no impact on the ground, 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 proof Cinder machine model, and therefore must be considered when mining method selection hydrogeological because 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.
