description The utility model relates to a mining tunneling supporting device, in particular to a mining joist supporting device which comprises a multifunctional operation platform. A joist lifting jack and a lifting device are arranged on the multifunctional operation platform, the joist lifting jack is obliquely arranged on the multifunctional operation platform, and the two ends of the hoist lifting jack are connected with the lifting device and the multifunctional operation platform respectively through connecting pins. The mining joist supporting device can improve work efficiency and lower labor intensity and working risks; a ceiling joist can be quickly hung on a front canopy through the device, under the condition that a roof is stable and roof caving does not happen, about 5 minutes can be saved for each time of erecting, in the working process, staff can not be hurt even if roof caving happens, the staff are prevented from working under a non-supporting empty roof operation environment, safety of operators is
