| 中文摘要: |
| 地质构造超前探测是保证煤矿高效生产与安全发展的关键技术。针对传统地球物理勘探技术无法实现深部巷道地质构造超前精准探测的问题，研究设计了基于频谱声学的地质构造超前探测新方法。首先，理论分析了巷道掘进中顶板岩层的谐振特性，阐述了利用弹性波属性反演煤岩体应力变化进行地质构造超前探测的基本原理；其次，搭建了连续监测与实时预警系统平台，研发了地震检波器和监测分站等系统硬件，开发了可人机交互操作的系统控制软件；最后，选取深部开采的典型代表平煤八矿己15-15080机巷进行了有效性验证。结果表明，地质构造监测指标高值区与地质构造揭露区相重合，在地质构造揭露前的一段距离，地质构造预测系数均会出现迅速增大并超出临界值的现象。相对应力系数在断层处的单侧、双侧或者整体出现高应力，这与地质构造演化情况相一致。按照掘进方向直线距离计算，超前预警距离为7.2~37.7 m，实现超前探测的可靠性高达92.85%。研究结果为深部巷道地质构造超前探测提供了高效可靠的新技术。 |

| Advance detection of geological structures is crucial for ensuring efficient and safe coal mine production. To address the limitations of traditional geophysical techniques in meeting the precision requirements for advance detection in deep roadways, a new method based on spectral acoustic was designed. First, the resonant characteristics of roof strata during roadway excavation were theoretically analyzed, and the basic principle of advanced detection of geological structures by inversion of stress changes of coal and rock mass with elastic wave attributes was expounded. Subsequently, a continuous monitoring and real-time early-warning system platform was established, with system hardware including geophones and monitoring substations developed, and interactive control software created. Finally, field validation was conducted at the Ji15-15080 machine roadway in pingmei eighth coal mine, a representative deep mining site. Results indicate that: High-value zones of the geological structure monitoring index coincide with exposed geological structures; The prediction coefficient shows a rapid increase exceeding the critical value within a certain distance ahead of structure exposure; Relative stress coefficients exhibit elevated stresses unilaterally, bilaterally, or entirely at faults, consistent with geological structure evolution. According to the linear distance in the driving direction, the advance warning distance is 7.2~37.7 m, achieving a reliability of 92.85% for advance detection. The research results provide an efficient and reliable new technology for advanced detection of geological structure in deep roadway. |
