For the need of mechanized upward middle-deep hole charging in underground mines,JFZ600 powder loading truck for underground middle-deep hole has been developed successfully. This paper presents the main parameters and construction features of the loading truck. The experiment indicated that the loading truck is reasonable in whole design,and is safe and reliable to use,its main indexes can satisfy the requirement of mining. The occurrence of the loading truck can effectively solve the imperative problems of associated loading explosive equipment in mines.
