| 摘 要： | 在华北、华东及西北地区近20多个煤田的石炭二叠系中，普遍存在着因煤系地层基底厚层灰岩古岩溶塌陷形成的煤层陷落柱，尤以山西省西山及汾河沿岸的煤田、河北省太行山中段的煤田更为普遍。煤层陷落柱发育形态分为圆锥形、筒形、斜塔形、不规则形等特点，应用高分辩地震勘探技术，根据陷落柱发育区反射波同相轴中断、扭曲、能量变弱、连续性变差、分叉合并或圈闭、产状突变等特征，可有效地探测其空间位置及形态。

| Abstract: | In more than 20 Permo-Carboniferous coalfields in North China, East China and Northwest China, coal seam subsided columns formed by collapsed coal measures basement thick-bedded limestone ancient karst, especially in coalfields in Xishan and Fenhe riverain coalfields in Shanxi Province and coalfields in middle sector of Taihang Mountains in Hebei Province. The coal seam subsided columns have conical, cylindrical, leaning tower and irregular patterns. According to phase axis characteristics of breaking off, distortion, energy weakening, continuity tailing off, bifurcating, merging or trapping, occurrence mutating from high resolution seismic, prospecting can detect their spatial location and shape effectively. |
