摘　　要：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。Sujiaping iron ore body is under Luoqunyan coal body.The distance form the top of fomer to the bottom of of the latter is only 60m meters apart.In this paper,the heights of roof caving of tunnels,and broking and subsidence of rock strata in Sujiaping iron mine after excavation are analyxed and calculated.The results show that even if it is collapse that all of the prospeting tunnels of Sujiaping iron mine in extreme cases,the safety of the upper prospecting work of Luoqunyan coal mine is not threatened.The paper draws a conclusion that the mineral prospecting work of Sujiaping iron mine can be carried out with the Luoqunyan coal mine in the same time.

关 键 词：顶板冒落 岩层变形 地表下沉 探矿巷道
