Inflatable mining rubber support

Supports in mining roadways need to be removed timely along with advancing of working planes of underground coal mines. If shed supporting is adopted in the mining roadways, supporting materials are difficult to recover and buried underground; if an individual hydraulic prop is fittingly adopted with a top beam support, cost is high and support service life is limited; in addition, along with deepening of coal mining, roof weighting happens frequently, a rigid support can be damaged due to plastic deformation under such high impact. Application of a plastic inflatable rubber support which is low in cost and easy to recover is a solution. When the support is used for supporting, the support is inflated, the inflated support swells to be contacted with a top plate, and accordingly a supporting function is achieved while pressure suddenly applied to the support can be buffered to protect the support from being damaged under sudden weighting; when the support needs to be removed, the support is deflated and then
