摘　　要：为了准确获取矿井综采地质条件情况,进行综采场地快速圈定,根据综采对地质条件的特殊要求,提出了一套较完善的评价指标体系,研究了评价结构与指标量化方法,采用了分维值作为刻画构造复杂程度的评价指标,并实现了分维值的自动计算.建立了基于GIS的综采地质条件模糊综合评价模型,基于GIS组件MapX开发了综采地质条件模糊综合评价系统,快速获取评价过程中所涉及到的各种指标数据,并对综采块段动态进行评价.评价模型在刘桥二矿得到了应用,获得了各评价采区地质条件优度值,给出了评价采区煤炭资源的开采工艺和最优开发接替顺序,为综采场地的快速选择提供了保障.In order to make clear the geological conditions suitable for fully mechanized coal caving so as to quickly locate the right area for fully mechanized mining, we proposed a set of evaluation indices according to the requirements of fully mechanized mining for geological conditions and studied the assessment structure and methods of quantifying these indices. Adopting fractal dimension values to describe the complexity of the structure, we realized the automatic calculation of fractal values. In addition, we built a GIS-based fuzzy synthetic assessment model for geological conditions suitable for fully mechanized mining and developed the system for the fuzzy assessment based on GIS ComGIS-MapX so as to dynamically acquire various data needed for the assessment. The model was applied in Liuqiao NO. 2 coal mine, obtaining preference values of geological conditions, exploitation technique, and the optimal succeeding sequence of mining, ensuring the fast selection of fully mechanized mining site.
