因生产进度的需要及各项条件的限制,采用普通钻爆法施工罗河铁矿破碎回风井天轮硐室,确保罗河铁矿的早日投产。天轮硐室的施工,直接影响到破碎回风井的施工进度及安全,因此,如何做到天轮硐室的高效、安全以及高质量的施工,是摆在建设方及施工方面前的大难题。 Because of the need of production schedule and the restriction of various conditions, Ordos Drilling and Explosive Method was used to construct Luohe Iron Mine to crush the celestial chamber of the return air shaft to ensure the early commissioning of Luohe Iron Mine. The construction of the coaster chamber has a direct impact on the progress and safety of the construction of the crushing return air shaft. Therefore, how to achieve the efficient, safe and high-quality construction of the coaster chamber is a major issue before construction and construction problem.
