摘　　要：龙矿集团北皂矿H2103工作面是海域开采第二个工作面,在首采工作面开采以后,H2103工作面开采,开采范围扩大,开采相对充分,研究发现:其矿压显现的规律更符合海域下三软煤层开采的实际规律,对实现安全高效开采具有参考指导价值。H2103 Workface in Beizao Coalmine of Longkou Coal Mining Group Co. Ltd. is the second workface in the Mining of Sea Area. After the First Workface, H2103 Workface Mining, the spread of exploitative range, the full exploitation of more. Its mine pressure behavior law is more comply with the law of the actuality under the ＂three-soft＂ coal seam mining laws in the Mining of Sea Area. The study is of reference value for security, more efficient exploitation.
