Preferably, described spillplate is old belt.
Preferably, on described spillplate, be evenly provided with several and unload power hole, to reduce the suffered Blasting shock wave of spillplate.
Preferably, described spillplate is comprised of two sections of above old belts, and two sections of adjacent old belts connect successively by bearing pin.
Compared to the prior art, tool has the following advantages blasting procedure coal mining special purpose device of the present invention:
1, when coal blasting the coal gear that rushes at goaf in drag conveyor, transport, realize explosion after the effect of coal automatic catch dress, and greatly reduce quick-fried fall coal cinder and the directly shock to individual prop and oil cylinder of horsestone, reduce maintenance of equipment rate.
2, select flexible old belt as spillplate material, not only reduced material cost, and reduced explosion and rushed energy.
3, on spillplate, spillplate suffered Blasting shock wave when coal blasting can be reduced in the hole of some orderly distributions, reduces the impact strength of spillplate when coal blasting.
4, spillplate material adopts multi-segment structure to be convenient to the installation of spillplate and the debugging of height, to adapt to the variation of different mining heights and condition.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described.
Accompanying drawing 1 is the structural representation of blasting procedure coal mining special purpose device;
Accompanying drawing 2 is the spillplate connection diagram shown in Fig. 1.
In figure: 1, top board; 2, the first pillars; 21, the second pillars; 22, the three pillars; 23, the four pillars; 3, spillplate; 4, ramp plate; 5, main fixed head; 6, drag conveyor; 7, leg; 8, hook; 9, bearing pin; 10, bolt; 11, moving device.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
Blasting procedure coal mining special purpose device of the present invention is applied in one work area, colliery, Jinyang, and the gear coal while completing bursting work and from process of assembling thoroughly solves the passive situation of pedestrian's difficulty after blast mining face bursting work in the past.It is safe and smooth that work plane can remain.Be that 3210 work planes have been created good security context, meet the safety requirements of face-airing, pedestrian and transportation aspect, realize security civilization and produce.
As illustrated in fig. 1 and 2, blasting procedure coal mining special purpose device comprises top board 1, the first pillar 2, spillplate 3, ramp plate 4 and drag conveyor 6, and for adapting to work plane mining height and intermediate channel height, spillplate 3 is collapsible spillplate, four spillplates, consist of, centre connects with bearing pin.For reducing spillplate 4 suffered Blasting shock wave when the coal blasting, on spillplate 3, be provided with in order several and unload power hole.For reducing material cost and reducing explosion punching energy, spillplate 3 is selected flexible old belt.
The upper end of spillplate 3 is connected with top board 1 by hook 8, the lower end of spillplate 3 is connected with the upper end of main fixed head 5 by bearing pin 9, spillplate 3 is the devices that rush at goaf direction coal while blocking coal blasting, and he is arranged on the main fixed head 5 of drag conveyor 6 near goaf side chute.When coal blasting the coal gear that rushes at goaf in drag conveyor 6, transport, realize explosion after the effect of coal automatic catch dress.
One side of main fixed head 5 is connected with pillar 2 by leg 7, and the opposite side of main fixed head 5 is connected with one end of drag conveyor 6 by bolt 10, and the other end of drag conveyor 6 is connected with ramp plate 4 by bolt 10.Wherein, ramp plate 4 is towards rib.
In addition, the first pillar 2 is DH22-468/125S monomer external poured; Drag conveyor 6 is SWG-30B type;
We do a simply description to whole coal mining process below:
Colliery mining height 2.2m, cyclic advance 0.8m, work plane adopt gradation powder charge, and gradation is detonated, and each blasting work face width 5m(here said wide 5m refers to single step of releasing gun commander degree, be work plane along inclined direction blow out length), series connection line.Pillar is arranged: first row is the first pillar 2, and second row is that the second pillar 21, the three pillars 22 are the anti-down canopy of lifting, the second pillar 21 and the 3rd pillar 22 interlaced arrangement, and the 4th pillar 23 is the single post of caving line.
Moving device 11 is hydraulic pushing machine, or claims to move to slip jack, is the double-acting hydraulic mechanism of a kind of internal liquid return.Can realize the passing of coal face of blasting mine in underground coal mine or common mechanical coal face scraper conveyor, its arrangement is, along floor undulation, every three meters, be evenly arranged, front end is fixed on drag conveyor 6, rear end is fixed on the 4th pillar 23, and spillplate 3 is close to the first pillar 2 after hanging up.The circulation of mining can be sketched and is: fluid injection → electric coal drill perforating → hanging spillplate 3 → powder charge → explosion coal-falling → fluid injection → linked network is propped up the forestope → rear float coal → moving device 11 of spillplate 3 → scraper cleaner conveyer 6 of coalingging → transfer and passed drag conveyor 6 → ramp plate 4 coaling → move frame → fluid injection → cut net Sub-Level Caving → net mending to block up coal discharge outlet → fluid injection → repair apparatus.For effectively completing automatic catch process of assembling, must make spillplate 3 rear portions have a firm support, this just must make more than the setting load of each hydraulic prop must reach 90KN, to be used for resisting the impact force of coal blasting to spillplate 3.
