Development and application of support operation platform mounted on mine boom type roadheader

In order to realize the technical requirements between the mechanized rapid driving and the coordinative matched technology of the U-shaped shed support,a support operation platform mounted on the boom type roadheader was reached and developed and a general structure plan and technical parameters of the operation platform were set up. The operation mode of " a grading control and sequential expansion" was applied to the operation platform. The manually erected beam was upgraded to a mechanized erected beam and thus the setting time of the U-shaped shed support was reduced. The industrial trial of the operation platform was conducted in a seam gateway driving in Linancang Mine. The site measurements and test showed that the matched application of the operation platform and the boom type roadheader could reduce the support time by 22.2%,a daily driving rate was increased from the previous 6.3 ~ 7.0 m to 7.7~ 8.4 m and the driving rate was increased by 20% in average.
