Description

technical field [0001] The invention relates to a head-on temporary support device for an excavation working face. Background technique [0002] Temporary support is a support for temporarily maintaining the stability of the surrounding rock and ensuring the safety of the working face in the coal mine roadway. There are independent type and airborne type for temporary support. For example, the advanced support machine disclosed in the utility model patent specification of Chinese Patent No. ZL 200820219641.6 is an independent temporary support machine, which can realize the functions of advanced temporary support and self-moving by stepping. Under the action of the expansion oil cylinder, the roof is supported. The airborne temporary support is used in conjunction with different loading machines, for example, a bolter with temporary support disclosed in the Utility Model Patent Specification of Chinese Patent No. ZL200920031700.1. The Chinese patent No. ZL03220384.5 discl...
