智能综放工作面在地质条件简单的矿井已经得到应用,但在地质条件复杂情况下综放工作面应用甚少。究其原因是构造、瓦斯、水等灾害影响着工作面正常回采,同时放顶煤过程地质依据性不强。以建庄煤矿4-2302综放工作面为例,结合综合地质探测工程,利用多源数据融合技术,构建高精度工作面多属性模型,采用地质模型剖切技术,生成地质截割曲线,发送至智能综放控制中心,配合综采三机精准控制,实现综放工作面基于透明地质的智能开采和放顶煤。现场试验结果表明,该技术提高了采煤效率,实现智能化综采放顶煤,为同类型复杂地质条件矿井实现智能开采提供经验借鉴。

ly applied under complex geological conditions. The reason is that the structure, gas, water and other disasters affect the nor-mal mining of the working face, and at the same time, the geological basis is not strong during the process of fully mecha-nized top caving. Taking 4 - 2302 fully mechanized caving face of Jianzhuang Coal Mine as an example, combined with com-prehensive geological exploration project, and using multi-source data fusion technology, a high-precision multi-attributemodel of the working face is built, adopting geological model profile-cutting technology, geological truncation curves are gen-erated and sent to the intelligent fully mechanized caving control center. Together with the precise control of three machinesof fully mechanized caving, the intelligent mining and top coal caving are realized in the mechanized caving face based ontransparent geology. The practical application proves that the technology has improved the efficiency of coal mining and real-ized intelligent fully mechanized top coal caving, providing reference for the realization of intelligent mining in mines withthe same complex geological conditions.
