摘　　要：综采综放采区地质条件综合评价的目的是根据评价单元条件对相关开采工艺的适应程度进行综合评价。该评价系统的指标体系包括地质条件(煤层、煤质、地质构造和岩浆岩)和开采技术条件(工程地质条件、水文地质条件等),评语集可按评价因素的分级来确定。因评价指标体系具有层次性和模糊性的特点,多级模糊综合评价法是较为适用的评价计算方法。因素的权重可采用专家调查法与层次分析法相结合的方法确定。文中利用上述模型建立了综采综放地质条件综合评价系统,并对即将开拓的某矿5#,7#采区进行评价计算。结果表明,5#采区能进行综采综放开采,7#采区较适合综采综放开采。从而为煤炭资源高产高效、安全开采提供了科学指导。The aim of geological conditions comprehensive evaluation of mechanized top-coal caving mine section is to evaluate the flexibility of evaluation unit to the mining technology. Factors of index system include geological conditions （coal seam, coal quality , structure and magma rock） and mining conditions （engineering geology conditions, hydrological geology conditions and others）. The comment assemble can be determined by level division of index system. Multilevel fuzzy comprehensive evaluation is the suitable algorithm because the index system has the characteristic of multilevel and fuzzification. Weight of factors can be assessed by AHP combining with expert investigation. Evaluation system was built according to the above model and calculation of No. 5 and No. 7 mine section of a coal mine was conducted. The results indicate that 5^# mine section can be exploited by mechanized top-coal caving technology. 7^# mine section is suitable for mechanized top-coal caving.
