Summary: | The invention relates to a fully mechanized coal mining face expansion safety parallel operation process, which comprises the following steps of: cutting a through guide roadway in a working face, and opening an assembly chamber with the same width and the same height as the guide roadway on the side of a machine roadway; the sliding type temporary supporting device, the bridge type reversed loader and the integrated excavator are conveyed to an assembly chamber to be installed in place, during slope expansion, the integrated excavator enters the position below the sliding type temporary supporting device to conduct tunneling operation, and slope expansion and installation are conducted synchronously. According to the method, the traditional operation mode that the fully-mechanized mining open-off cut is installed after brushing and expanding is changed, synchronous integrated operation of the two working procedures of fully-mechanized mining open-off cut, brushing and expanding and equipment installation is |
