摘 要:煤炭开采方式受开采地质条件控制。开采地质条件包含多种因素,每一因素对采矿方式的适应度没有明显的界限,只是模糊概念。将影响金鸡滩井田煤炭生产的地质因素分为煤层赋存特征、构造发育特征和其他因素3大类以及14个评价因子;采用"降半梯形"法和专家打分法确定其隶属度和权重值;通过二级模糊综合评判,结果显示,金鸡滩井田比较适合机械化综采。经与同一矿区内邻近生产矿井类比,评判结果是合理的。Coal mining method is controlled by mining geological condition which contains many factors.Each factor has influences on the mining way, but the adaptability of factors has no apparent limit, but only with fuzzy concept. The geological factors, in fluencing coal mining way of Jinjitan coal field, are derided into three kinds including fourteen evaluating factors. Their membership and weight value are determined with "step-dowm trapezoid"method and expert system. After the two step fuzzy comprehensive evaluation, it is considered that the mining geological condition in Jinjitan mine fits for mechanized comprehensive mining. The analogue analysis of mining area and adjacent mines indicated that the evaluation result is reliable.
