Abstract: Water damage is a frequent major diseases existing tunnel, leakage of water in cold regions is an important factor affecting heaving rock tunnel. In this paper, the existing operators Shenyang Railway Bureau tunnel water leakage survey, exploration and measurement of disease, the degradation mechanism of water seepage analysis, watershed remediation works typical tunnel tests selected. Classification regulation for their different causes water leakage, the use of block, row, cited the comprehensive management of technology, leakage of water moving under conditions of rapid closure of the water chemical grouting materials suitable for cold regions selected Malisan various tunnels. After engineering verification, leakage of water from the tunnel to get a fundamental governance, successfully resolved the existing operational railway tunnel seepage water problems for our existing tunnel seepage water governance provide a reliable basis, has broad application value.

Abstract: Piles and dumps in mining sites of lignite and ore mines very often generate drainage water with a low pH value. Furthermore they are contaminated with heavy metals or radionuclides. A comprehensive sustainable remediation and / or a water treatment process requires an assessment of the water quality and the determination of the future development thereof. This, in turn, requires prediction of the microbial processes which are responsible for the release of heavy metals and radionuclides. The paper deals with the demonstration of a suitable method for the prediction of these reactions and water quality.
