Heilongjiang Nen water conservancy project. River water diversion project environmental impact analysis is the construction of a very important research topic, with quite significant diversion project on the feasibility of the decision-making. In this paper, Nierji Hydro built to run as a precondition for the expansion of Heilongjiang Nen a project on the impact of the Nen River water environment were studied. The study includes: a project to predict the impact of the Nen River hydrological regime, a project the Nen River water quality impact analysis. Paper a numerical simulation model, developed by the Danish Hydraulic Institute's MIKE11 software for solving the model to predict the impact on the water regime; the use of comparative analysis method to evaluate the impact on water quality. By studying that: the impact of a project on the Nen River diversion of river runoff mainly by Nierji reservoir drainage control, the Nen River in downstream water flow has a relatively large change in the tunnel loading machine parts, in particular dry years (p = 90%) of 8,9,10 month, the Nen River diversion on the hydrologic regime of the larger tunnel loading machine configuration, there is no impact of non-diversion period, Qiqihar Fulaerji section driest month flow to meet 35m ~ 3 / s Rivers environmental water requirements; changes and increased irrigation return flow of the hydrological regime of the Nen have some impact on water quality. China is the production of slag 巩义鑫 professional manufacturers willing to sacrifice the power of livelihood projects to this end!

Deposits may fill some of the upper-day mining tunnel for loading machine model, the lower for underground mining. Either way under exploitation, 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.
