Abstract
Light top-coal caving hydraulic support is one of the main equipment in light top-coal caving face,the reasonable and reliable support type determined the safe and effective production of light top-coal caving face.According to the coal seam occurrence characteristics of thick and high gas in one mine,through theoretical calculation and analysis in the basis of the roof and floor classification of coal seam,the light top-coal caving support type that is suitable for the high gas and thick coal seam was selected.
