Embodiment 1
[0062] Embodiment 1, a filling method, using a gob-side entry retaining horizontally inclined double-stretched fiber flexible formwork, such as Figure 6 As shown, it is specifically implemented in the following ways and steps;
[0063] Step 1. According to the size of the position that needs to be filled between the roadway roof and the roadway floor in the gob-side entry retention, use wooden point columns 14 on the side of the goaf to block gangue support, and use single hydraulic props 15 on the side of the gob-side entry retention roadway Hanging nets to block gangue support;
[0064] Step 2. According to the length of filling, place several flexible formworks of gob-side entry retaining with double-stretched fibers;
[0065] Step 3. According to the size of the filling height, select the sleeve 11 on the top transverse flange 3 of the main body formwork 1, and penetrate the steel bars, and at the same time wear the steel bars on the transverse flange 3 in the middle of ...
Embodiment 2
[0073] Embodiment 2, a filling method, using a gob-side entry retaining horizontally inclined double-stretched fiber flexible formwork, such as Figure 7 As shown, it is specifically implemented in the following ways and steps;
[0074] Step 1. According to the size of the position that needs to be filled between the roadway roof and the roadway floor in the gob-side entry retention, use the gangue-blocking hanging formwork support 13 on the side of the goaf to block gangue support, and use the single hydraulic pressure on the side of the gob-side entry retention roadway. Pillar 15 hangs the net and carries out gangue retaining support;
[0075] Step 2. According to the length of filling, place several flexible formworks of gob-side entry retaining with double-stretched fibers;
[0076] Step 3. According to the size of the filling height, select the sleeve 11 on the top transverse flange 3 of the main body formwork 1, and penetrate the steel bars, and at the same time wear th...
