| 摘 要： | 矿井安全生产受前方采空区、断层破碎带等复杂地质因素制约，矿井槽波超前探技术的逐步完善提高了采空边界、断层的探测精度，提高了对掘进前方隐伏地质灾害预报的准确率。为保障复杂地质条件下矿井安全、高效生产，开展槽波采空边界探测理论分析十分必要。数值模拟探测结果说明，槽波超前探测在技术上可行，利用人工设置断层，然后进行后期数据处理，验证在槽波成像界面处确实是断层构造，为煤岩界面，裂隙较发育，岩体较破碎，同时也验证了提出的后期数据处理思路有效、可靠。

| Abstract: | Colliery safety production is severely constrained by some complex geological factors，such as goaf and fault fracture zone ahead. The development of mine exploration advance wave groove technology has gradually improved and the detection accuracy of mined border and fault，and has improved the accuracy of buried geological disaster forecast of later driving. To ensure the security and efficiency of mining production under complicated geological conditions，it is necessary to carry out theoretical analysis on mined border exploration by using channel wave. The results of numerical simulation were used to illustrate the feasibility of trench-wave advance detection. The artificial faults were set up and the data were processed later. It was verified that the tidal wave imaging interface is a fault structure，which is a coal-rock interface，fissures developed，broken. Therefore，it has been validated that the post-data processing ideas put forward is effective and reliable. |
