摘　　要：介绍了龙口海域下开采的有利与不利因素,分析了海域下选择综放开采的原因;根据海域开采导水裂缝带的实测结果和断层条件下覆岩破坏规律的数值模拟计算,提出了综合考虑正常与断层条件的防水安全煤岩柱厚度;并介绍了海下开采安全技术措施。Favorable and unfavorable factors of mining under sea are analyzed in this paper after introducing the cause of selecting fullmechanized caving mining. Based on measurement result of water-conductive fissure zone and numerical simulation of broken rule of underlying rock, height of protective pillar against water under ordinary and fault condition is obtained. Safety measure of mining under sea is introduced as well.
