Abstract：Sealing the poor test holes has a certain risk to the working faces, and determining its risk can provide technical and decision-making basis for the water prevention and control of the holes. Based on the fuzzy comprehensive analysis, a fuzzy risk assessment model for the test hole was established. The model contained six hole risk evaluation indexes including the hole sealing position, the hole sealing quality, the mudstone content in the exposed section, the structural development, the exposed water-bearing bed or water body and the expected water inflow as well as the risk classifications standard and its corresponding fuzzy value. The model used the normal distribution membership functions to determine the fuzzy membership matrix and adopted the entropy weight method and analytic hierarchy process to determine the weight of the evaluation indexes. Finally, through the matrix operations, a comprehensive assessment was carried out on the risk of No. 10 test hole in Beizhao Coal Mine, and the efficiency analysis and weighted analysis were made on the evaluated results, the evaluated result accorded with the actual situation.
