Research and application of full length recoverable resin metal bolt to Huayuan Mine

A full length recoverable resin metal bolt is a new bolt applied to the sidewall of the mining gateway in the mine with a good anchoring effect and recoverable advantage for reapplication.Due to the restriction of the geological condition,the length of the coal mining face in Huayuan Mine of Jining Coal Mining Group is short and the service period of the mining gateway is short.The trial application showed that the full length recoverable resin metal bolt could be suitable to the seam condition.The bolt could be obviously to improve the support effect of the mining gateway,could reduce the support cost of the mine and would have a important significance to reach the mining energy saving and the emission reduction targets of the mine.
