煤炭地质勘查类型反映了在不同地质勘查条件下勘探方法的特点和不同历史时期构造、经济政策和勘探经验。划分勘查类型不仅有助于合理的选择勘查工程密度、经济地划分开采技术条件、准确地划分各级别资源储量，还可为煤矿设计和生产提供必要的地质数据。 地质构造复杂程度和煤层稳定程度是现行《煤、泥炭地质勘查规范》划分勘查类型的两项主要指标。本文以前人的研究为基础，分析有关地质构造复杂程度、煤层稳定程度和勘查类型定量划分存在的问题，提出具体的解决方法。通过查阅相关文献，搜集大量勘探资料，梳理目前构造复杂程度的定量指标体系，提出用综合指数法建立地质构造复杂程度定量划分标准，并结合MATLAB语言编写模糊神经网络程序，建立地质构造复杂程度定量划分模型。针对煤层稳定程度，通过分析煤层厚度和形态变化的影响因素，将趋势面分析引入到数理统计方法中，提出用趋势变异法建立评价指标体系和划分标准，并根据灰色关联度分析法计算权重，用模糊综合评价法建立定量划分模型。 通过对华宁井田和西卓子井田构造发育规律和主采煤层赋存规律研究，用上述模型对地质构造复杂程度和煤层稳定程度进行定量划分，划分结果分别为简单类型和中等类型，与勘探时期的划分结果基本一致。

Coal geological exploration types reflect the characteristics of exploration methods, structures, economic policy and exploration experience in different geological prospecting conditions and historical periods. Dividing it not only contributes to rationally select exploration project density, economically divide mining conditions and each level of resources reserves, but also provides the necessary data for coal mine design or production. Geological structure complexity and coal seam stability are the main indexes to divide exploration types in the current coal, peat geological exploration norm. This paper is based on previous studies, analyzing the limitation of geological structure complexity, coal seam stability and quantitative division of exploration types. With collecting much of exploration data, proposing to use the comprehensive index method to establish index system and division standard, and combining with MATLAB language to establish the division model basing on fuzzy neural network method. To the coal seam stability, through analyzing the influencing factors of seam thickness and morphological change, the trend surface analysis is introduced into the mathematical statistics method, preferring to using trend-variation method to establish evaluation index system and standard, then calculating the weight with gray correlation analysis, using the fuzzy comprehensive evaluation method to establish the division model. By studying geological structure and coal seam of occurrence regularity in Hua Ning and Xi Zuozi mine field, using the upper models to quantitative divide the geological structure complexity and coal seam stability, the result is simple and middle, which is consistent with the results of mine geology division type classification.
