| The research of underground water gushing is a very important topic in the production after entering the deep mine. The origin of the ground water, the size of amount of water, whether it having waterpower contact of the surface water and the ground water or not, the intimate degree of contact and its influencing degree to the dampness penetration of mining pit, which decide the complicated degree of the condition of hydrological geology of deposit and the important factor of mine design of waterproof and water control, are all very important problem need to resolve in the hydrology research of mining area and the important bases of the mine security, the mine drain and the design of deposit draining. The condition of hydrological geology is relatively complexity and the contact of waterpower is quite intimate especially in karst mine area. It decides the production and construct project of mine, the scale of investment, the production cost of ore and production economic benefit of mine and affects the confirmation of the project of mining water control which can forecast amount of water gushing of deposit. So, the research of water gushing to Malu after entering the underground has important realism meaning.The paper has investigated and researched the resource and the route of dampness penetration in the mine based on the wide investigating and collecting data and educed the conclusion that the gushing mostly come from the rainfall and amount of water unable to increase along with the falling of exploitation. At the same time, the paper has discussed the calculation and the theory of inflow of water in the mine and forecasted amount of water in the mining pit by the analysis method and the regression equation and put forward a suit of systemic prevent or control flood and water-control measure at the up and down of the mine aim at the physical circumstances, which provided valuable reference for the formulate of water proof and water-control design in the mine.
