罗群岩煤矿与苏家坪铁矿的矿体重叠,上下仅相距60m左右。两矿同时开展探矿工作或有潜在的安全影响。分析计算了苏家坪铁矿探矿的顶板冒落高度、岩层破裂高度与岩层变形下沉高度。分析表明,即使在苏家坪铁矿探矿巷道垮塌的极端情况下,也不会对上部煤矿勘查活动构成安全威胁,进而提出了两矿可同时实施其探矿工作的结论。
Luo Qun rock coal mine and Sujiaping ore overlap, up and down only about 60m apart. Both mines carry out prospecting work at the same time or have potential safety impacts. The roof caving height, rupture height and rock deformation height of Sujiaping iron mine are analyzed and calculated. The analysis shows that even in the extreme case where the tunnel of Sujiaping iron mine collapses, it will not pose a safety threat to the exploration activities in the upper part of the coal mine, and then concludes that the two mines can simultaneously carry out their prospecting work.
