| Mine water inrush is an important natural disaster during mining. To judge the composition of mine water inrush accurately plays a significance role in solving this issue. This article takes Maluping mine as an example to analyze the composition of water mine inrush, and analyze the characteristic of its hydro-chemistry based on investigation in mine geology, hydrological data and water inrush conditions. On the basis of the result of hydro-chemical analysis, we established multi-mixture and fuzzy comprehensive evaluation analytical model respectively. At the same time, we take advantage of two methods to judge the composition of mine water inrush. After that, we combine domestic and overseas solutions as a reference to analyze Maluping Mine’s water inrush problem, putting forward relevant suggestions, the specific results we obtained are as follows:(1) The source of water inrush is atmospheric precipitation, underground water and industrial consumption. The mainly channels for water inrush are faults, seams and subsidence.(2) Multi-mixture model as a newly method can calculate water inrush mixing ratio effectively.(3) The main source of water inrush of Maluping Mine is underground water. The more advance of mining depth, the larger proportion of underground water in mine water inrush, while the surface water affects decreased.(4) Based on the current situation of Maluping mine water inrush, we advised the following methods:setup several unwatering schemes in coping with water inrush. The measures of construction of catchwater drains, back fill collapsed holes and build dams are put forward to solve surface issues. |
