轻型低位放顶煤开采适应性技术研究

Research on Adaptability Technology of Light Type Low Position Caving Coal Mining

镇城底矿地质构造复杂,轻型低位放顶煤综采支架在该矿得到了较好的应用。从采用轻型低位放顶煤开采,可实现灵活多变的巷道布置、对煤层薄厚的适应及过断层等方面的特点进行了系统的分析,说明了该型支架对复杂地质条件的适应性。

Geologic structure of Zhenchengdi coal mine is complex, the comprehensive mining support type low position caving coal obtains very good application. From using the light type low position caving coal to realize the flexible tunnel arrangement, to adapt to the coal seam thickness, passing through the fault an characteristics carries on systemic analysis, explains the adaptability of this support to the complex geology.
