| 摘 要： | 山西晋城矿区内沟谷发育，地形复杂，最大相对高差400m，浅层地震地质条件以裸露基岩为主，少部分是黄土和坡积物覆盖，表浅层地震地质条件非常复杂。区内山西组3#形成的T3波形突出、全区稳定，可连续追踪对比；15#煤层因3#煤层的屏蔽作用，反射波T15波能量较弱。针对该区的地震地质条件，在不同地段分别选用空压机配风镐、山地钻、洛阳铲等成孔工具，以保证激发层位在未风化基岩中。基岩中激发获得的原始资料信噪比较高，小构造反映清晰，可见改善激发条件可为资料解释提供可靠依据。

| Abstract: | There is complicated terrain with developed ravines in Jincheng mining area, Shanxi, maximum relative elevation 400m. Near-surface seismic-geologic condition is very complex with mainly outcropped bedrocks, a few loess and talus. The T3 waveform of No.3 coal, Shanxi Formation is conspicuous and steady in the whole area, can trace and correlate in succession; the No.15 coal as guarded by No.3 coal, the reflected T15 wave is weaker. Based on the seismic-geologlc condition in the area, respective tools such as pneumatic pick, boring rig for mountainous areas and the Luoyang spade are selected for different sectors to ensure shotpoint is within fresh bedrock. Primary data acquired with shotpoints in bedrock have higher S/N ratio and clearer minor structure reflection, thus the data interpretation is reliable. |
