| Abstract: | Through analyzing the mechanism of combined support with metal resin bolt,strip,shotcrete in the no-hard roof and dynamic pressure compound roof,the shortages of passive pressure,low utilization rate and large maintenance amount in the traditional shelf-supporting are pointed out.The influence factors on the construction quality with strengthening the blasting control are proposed.The effect range of anchor,strip and shotcrete is discussed. |
