It sets so that upper support bar erects, so that upper support bar is supported the front end of forestope by upper hydraulic stem；
3) staff completes lapping, networking and Anchor Care operation on workbench, realizes to top plate exposed in tunneling process
Permanent support；
4) retraction for passing through side hydraulic stem and upper hydraulic stem makes two by the second horizontal hydraulic cylinder so that upper support bar is recycled
Grade supporting platform retraction, and vertical support is made to bounce back, by first level hydraulic cylinder level-one supporting platform is bounced back；Meanwhile
The lifting hydraulic cylinder of workbench is overhanging, the position for the top coversheet about 200mm for rising to platform body apart from main support, main branch
The lifting column of frame bounces back, and declines the top coversheet of main support slightly, disengages with back, then passes through main support
Passage cylinder extension between secondary support, and using secondary support as fulcrum, drive main support to move forward；
5) lifting column of main support is overhanging, and the top coversheet of main support is made to be supported on the tunnel for just having realized permanent support again
Top plate；Meanwhile the lifting column retraction of secondary support, it disengages the top coversheet of secondary support with back, passes through main branch
Passage hydraulic cylinder retraction between frame and secondary support, using main support as fulcrum, makes secondary support move forward；It, will after secondary support moves forward
The lifting column of secondary support is overhanging, so that the top coversheet of secondary support supports back again；
So far, a working cycles are completed, the development machine that reruns carries out cutting to tunnel coal petrography wall, starts to carry out next work
It recycles.
