摘要
The refuge chamber has been widely accepted as a necessary part in the emergency rescue system of the coal mine because they can be conveniently installed and moved in the underground workplace. The refuge chamber's cabin should have an excellent anti-explosion performance to the impulsive load resulted from an explosion, which is necessary for the normal operation of its internal systems. In this paper, by the combination of theoretical analysis, numerical simulation and experiments, the anti-explosion performance of KJYF-96/8 type coal mine refuge chamber's cabin was studied. Firstly, according to the working condition, a behavior model characterizing the gas and coal dust explosion was established. Secondly, the anti-explosion perfoiuiance of the cabin was numerically simulated and then analyzed. Furthermore, the gas and coal dust explosion experiments were carried out in an underground laneway. Based on these works, the variation curve of the equivalent triangular impulsive load wave with the change of time, the maximal stress and deformation of the cabin in explosion, and the damage of the cabin in the actual explosion test were obtained. It is found that the newly-designed KJYF-96/8 type coal mine refuge chamber can meet the anti -explosion requirements.
