摘　　要：本文通过槽波和坑透2种探测技术对鹿台山煤业2203工作面地质构造进行超前探测,所发现异常区域的预测结果为煤厚变薄、夹矸变厚、断层发育引起的场强异常衰减,与实际回采揭露地质构造情况基本一致,说明本次超前物探具有较高的精确度。同时,通过对回采过程中地质构造附近瓦斯赋存规律进行总结分析,可对其他地质构造附近瓦斯涌出进行预测预报,从而指导工作面安全生产。In this paper,the geological structure of 2203 working face in Lutaishan coal industry is advanced detected by two detection technologies of trough wave and pit penetration.The prediction results of abnormal areas are the abnormal attenuation of field strength caused by coal thickness thinning,gangue thickening and fault development,which are basically consistent with the actual geological structure revealed by mining,indicating that the advanced geophysical exploration has high accuracy.At the same time,through the summary and analysis of the gas occurrence law near the geological structure in the mining process,the gas emission near other geological structures can be predicted,so as to guide the safe production of the working face.
