摘要
介绍了急倾斜突出矿井煤层群开采技术条件,并基于江西沿涌矿井的32采区开采,论述了急倾斜突出煤层解放层选择,通过对瓦斯突出强弱和保护层的顶板冒落高度数量分析,推荐了合理的突出煤层开采顺序,为矿井工作面接替和安全生产提供有力的保障。
The mining conditions in steep coal seams of the outburst mine are introduced.The selection of liberated seam in steep outburst coal seam is discussed based on the exploitation of 32th mining area of Yanyong Coal Mine.According to the analysis on datas of gas outburst strength and height of caving zone in roof of protective layer,the reasonable mining sequence in outburst coal seams is recommended.The favorable guarantee is provided for face replacement and safety production in mines.
