Abstract: A coal mine environmental protection coal shed needs to be removed for some reason. Now, the construction of environmental protection coal shed is more, but the case of demolition of this kind of project is rarely seen, there is no experience that can be used for reference. To this end, we have formulated a more elaborate dismantling plan. According to the characteristics of the arched grid, a number of safety measures are designed to make the dismantling work orderly and safe and stable. There are some experiences that can be summed up and some processes that are worth refl ecting on, which can be used as reference for similar projects in the future.
