摘　　要：分析了红会一矿小窑破坏区的特征和小窑破坏区综放工作面煤炭损失的原因,通过优化工作面几何参数、减少区段煤柱损失、研究工作面支架和配套设备适应性、选择合理的回采工艺以及确定合理的顶煤预先弱化等措施,提高了红会一矿小窑破坏区综采面煤炭的回收率,为保证安全高效地开采煤炭资源提供了有效途径。The paper had an analysis on the features of the failure zone occurred by the previous small mine in Honghui No. 1 Mine and the coal lost causes of the fully mechanized top coal caving mining face in the failure zone occurred by the small mine. With the optimization on the geometric parameters of the coal mining face, the reduction of the coal pillar lost in the section, the study on the suitability of the powered supports and matched equipment in the coal mining face, the selection on the rational mining technique, the determination on the rational pre - weakening of the top coal and other measures, the coal recovery rate of the fully mechanized coal mining face in the failure zone by the previous small mine in Honghui No. 1 Mine was improved and an effective access was provided to ensure the mine safety and high efficient mining of the coal resources.
