论述了乌鲁木齐煤矿急倾斜近距离厚煤层薄煤层轻放开采方法的科学性，避免了急倾斜近距离煤层的放顶煤影响，提高了生产能力和回采率，形成了通风系统标准化基础，采用液压支架放顶煤开采，保证了生产安全，适应联合开采后围岩破坏及矿压显现规律。为进一步推广综采工作面，完善工作面生产制度提出了建议。
The scientific of mining method on sublevel caving with light supports in the thinner of the steep close and thick seam in the Urumqi coal mine was discussed, the caving influence in the steep and close seam was avoided, the throughput and extraction ratio were improved, the standardization base of the ventilation system was formed, sublevel caving with hydraulic pressure support was used in order to ensure the working safety, adapt the destroying and the law of strata pressure appearance in surrounding rock after combining mining. The suggest were gave for extending of the combining mining and perfect producing system of working face .
