Application and development on new type walking self moving advance temporary powered support

According to an untimely support, low support strength, high labor, high cost and other problems existed in the temporary support method of the mechani zed heading face, a new walking self moving advance temporary powered support with safety reliability, operation simple and high suitability was developed and manuf actured. A framework sliding alternative walking structure system, steel mesh paving mechanism and bolt drilling platform were applied to solve the walking, steel mesh paving and permanent support problems of the powered support. The site experiment showed that the powered support could well suit the performance condition of the mine gateway, could timely make multi temporary roof supports of the mine gateway, could make the automatic steel mesh paving, could eliminate the procedure freque ntly changed, could realize effective parallel operations for the permanent support and temporary support, could simplify the labor organization and could improve the dr iving speed of the mine gateway. In comparison with the previous work efficiency of 0.21 m 1 man, the work efficiency was improved by 66. 7%.
