摘要
通过现场布置钻孔、钻孔分段注水试验、钻孔电视窥视及地表裂缝的实测等方法深入分析了内蒙古同煤鄂尔多斯矿业投资有限公司色连一号矿(以下简称"色连矿")浅表厚煤层开采覆岩裂隙发育特征及其动态演化规律,并提出了首采区2-2上煤层限高开采防控技术。
Drilling through the site、Sectional water injection test、Borehole television peep and The measured surface cracks. Deep analysis of development characteristics and its dynamic evolution rules of mining overlying rock fissure in shallow thick coal seam in Se Lian Mine.And put forward high limit control mining technology of 2-2 upper coal seam in the first mining area.
