基于模糊综合评判法的煤层底板突水危险性评价

摘要

煤层底板突水是受多个因素综合影响的，针对矿井水文地质条件与底板突水的复杂性和模糊性，为了更客观合理地评价煤层底板突水危险性程度，建立AHP-模糊综合评判模型，借助MatLab对运用GiS叠加出来的每个评价单元进行煤层底板水害威胁程度模糊综合评判，最后得到四个突水危险性等级在矿区所在比例，而不是从整体上笼统的得出矿区的底板突水危险性的等级。这样评价结果更为准确，也更加符合实际情况。%Coal floor water bursting is comprehensive affected by multiple factors ,in view of the complexity and fuzziness of the mine hydrogeological conditions and coal floor water bursting, in order to more objective and reasonable evaluation the risk degree of coal lfoor water bursting , we set up the AHP-fuzzy comprehensive evaluation model , then with the help of MatLab, making the fuzzy comprehensive evaluation of the risk degree of coal lfoor water bursting for each evaluation unit superposed by GIS , Finally getting the proportion of these four water inrush risk level in the mining area where, Rather than conclusion the lfoor water inrush risk level of mining area on the whole general. The evaluation results more accurate and in line with the actual situation.
