摘要(Abstract)：

煤矿地质保障技术是实现煤炭精准开采和绿色采矿的关键路径，针对智能开采需求和地质保障要求，分析了回采工作面地质保障主要面临的难题，包括基础理论研究薄弱、地质探测精度不足、建模精度无法满足工程应用、模型动态更新困难、缺乏基于时空演变的智能回采全局路径最优决策手段等。根据面临的难题和技术现状，对陕西延安黄陵一矿和陕西神木榆家梁煤矿智能开采地质保障技术进行了探索实践。黄陵一矿以810综采工作面智能开采为目标，采用综合探测、数据融合等技术，构建工作面静态地质模型，利用地质雷达、惯性导航技术，动态修正工作面地质模型，通过对“透明工作面”高精度地质模型“CT切片”，获取采煤机关键截割曲线，与回采工艺、装备形成耦合协同、联动控制模式，实现基于三维空间感知和智能数据分析的规划截割，推动黄陵一矿810综采工作面实现智能无人化开采。榆家梁煤矿提出构建基于时空数据模型的智能自主割煤工作面无人化开采模式，融合多源异构地质数据建立智能开采工作面多属性地质数据库，构建基于绝对坐标的43101工作面高精度时空地质模型，并基于时态地理信息系统平台(4DGIS)进行三维地质模型可视化，实现地质模型的任意剖切，结合随采地质雷达获取煤厚、煤层顶底板和煤岩界面数据进行动态修正，实现基于高精度地质模型的采煤机自主截割。通过2个案例对面临的难题进行有益的探索，最后进行总结与展望，为企业高质量发展指明了技术方向。
Coal mine geological guarantee technology is the key path to achieve accurate and green coal mining. In view of the requirements of intelligent mining and geological guarantee, the main problems faced by the geological guarantee of the mining face were analyzed, mainly including the weak basic theoretical research, insufficient geological exploration accuracy, modeling accuracy unable to meet the engineering application, difficulties in model dynamic updating,and lack of optimal decision-making means for global path of intelligent mining based on spatio-temporal evolution. According to the faced difficulties and technical status, the author explored and practiced the geological guarantee technology of intelligent mining in Yan'an Huangling No.1 Coal Mine and Yujialiang Coal Mine in Shaanxi. Taking the intelligent mining of 810 fully mechanized working face as the target, the integrated detection, data fusion and other technologies were adopted in Huangling No.1 Coal Mine to build a static geological model of the working face. Meanwhile, the geological radar and inertial navigation technology were used to dynamically modify the geological model of the working face. Besides, the key cutting curve of the shearer was obtained through “CT slice” of the high-precision geological model of the “transparent working face”. Thus, a coupling, coordination and linkage control mode was formed with the mining technology and equipment, to realize the planned cutting based on 3D space perception and intelligent data analysis, and further to promote the realization of intelligent unmanned mining in 810 fully mechanized mining face of Huangling No.1 Coal Mine. In terms of Yujialiang Coal Mine, it was proposed to build an unmanned mining mode of intelligent autonomous coal cutting face based on spatio-temporal data model, build a multi-attribute geological database of intelligent mining face by integrating the multi-source heterogeneous geological data, establish a high-precision spatiotemporal geological model of 43101 working face based on absolute coordinates, and visualize the 3D geological model based on the temporal geographic information system platform(4DGIS) to realize the arbitrary cutting of geological model. Then, dynamic correction was carried out with reference to the data of coal thickness, coal seam roof and floor,and coal-rock interface obtained by the geological radar while mining, so as to realize the automatic cutting of the shearer based on the high-precision geological model. Conclusively, a useful exploration of the difficulties faced was made based on two cases, with summary and prospect provided finally, thereby pointing out the technical direction for the highquality development of enterprises.
