| 摘要： |
| 为给某煤矿2204工作面安全生产提供地质依据，讨论了该工作面井下煤层中的断层、陷落柱及煤厚变化趋势。基于区域地质与采矿资料，采用槽波及滑行波勘探技术，通过地质资料整理、数据采集，以及建立观测系统、初至校正、滤波等数据处理流程，结合槽波及滑行波能量衰减CT图，综合探测工作面的地质构造情况并圈定其他异常区。结果显示：在工作面内解释出1条发育于停采线区域、落差＞1/2煤厚的正断层；划定2处煤层异常区（mc1、mc2），均为受断层影响形成；依据滑行波能量衰减图确定了2处底板异常区（db1、db2），其中，db1在10 m深度出现异常，推测为底板断层断裂带影响，往深部逐渐减弱，db2在10～60 m显示异常，推测为底板裂隙发育区。 |

| Abstract: |
| To provide a geological basis for safe production at the 2204 working face of a coal mine, this study analyzes the faults, collapse columns, and coal thickness variation in the seam. Based on regional geological and mining data, channel wave and refracted wave exploration techniques were adopted. Through data compilation, field acquisition, geometry setup, first-arrival picking, filtering, and other processing steps, combined with CT images of energy attenuation of channel waves and refracted waves, the geological structures within the working face were comprehensively detected and anomalous zones were delineated. The results reveal one normal fault near the stopping line with a throw greater than half the coal thickness. Two coal anomalous zones (mc1 and mc2) are identified, both interpreted as fault-induced anomalies. Based on the energy attenuation maps of refracted waves, two floor anomalous zones (db1 and db2) are determined. For db1, an anomaly appears at a depth of 10 m, which is inferred to be caused by a floor fault/fracture zone and gradually diminishes with depth. For db2, an anomaly is present in the depth range of 10-60 m, interpreted as a zone of developed floor fractures. |
