摘要： 为提高资源回收率，在豫西“三软”煤层矿区，进行煤层复采，回收残留煤炭。通过矿压观测与分析，获得了复采区工作面支柱工作阻力大于原始煤层区；工作面来压较明显；复采区工作面来压步距较短；复采工作面压力分布不均匀等矿压显现的重要特征，为复采采场支护和工艺技术研究提供了基础资料。
关键词: 三软煤层, 不稳定厚煤层, 复采工作面, 矿压观测, 矿压显现特征
Abstract: To increase the resources recovery rate, repeated mining and the recovery of residual coal resources is used in three-soft mining area of western Henan Province. Through strata control observation and result analysis, the important characteristics of strata behavior were obtained in repeated mining face, which is that working resistance of face support in repeated mining area is greater than in original seam, the periodical weighting is more obvious, the roof weighting step is shorter and roof pressure distribution is non-uniform, this discover provides an basic date to research on repeated mining technique and face support and has an important application value.
Key words: three-soft coal, unstable thick coal seam, repeated mining face, strata control observation, characteristics of strata behavior
