1)Lay one's hand on lid installation:After spilled water hole discloses, sluicing will be inserted directly into after laying one's hand on lid decentralization to working face by secondary hoisting gear In hole, core pipe and the floral tube part exposed are encased with one section of conveyer belt, colligation is firm;
2)The height control of tapping pipe:The high control of clear bottom section is in the range of 2.5m every time during normal driving, and spilled water hole is away from clear Exposed bottom working face is 0.4m, determines snubber drilling arrangement when drilling every time with the hole site that sluices;
3)Sluice protection of pipe during the clear bottom of working face:After the completion of the clear basic skill or training of working face makees, it will be let out using secondary hoisting gear
Water hole is laid one's hand on lid and pulled out, and gas cutting drain water circuit, drain water circuit is highly controlled between 300mm-400mm, then with pair Hoisting gear will lay one's hand on lid decentralization to being inserted directly into spilled water hole after working face, with one section of conveyer belt by core pipe and the floral tube portion exposed Subpackage is lived, and colligation is firm;
4)Sluice protection of pipe when working face is levelling:After the completion of the levelling work of working face, it will lay one's hand on lid using secondary hoisting gear and draw Go out, gas cutting drain water circuit, drain water circuit is highly controlled between 300mm-400mm, and secondary hoisting gear will lay one's hand on lid decentralization and directly insert Enter in spilled water hole, carry out borehole wall concrete casting and constructing;
The beneficial effects of the invention are as follows:This equipment is put into spilled water hole, effectively prevents broken spoil from blocking spilled water hole;Behaviour Facilitate, there is provided operating efficiency.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention;
Fig. 2 is Fig. 1 top view;
Fig. 3 is mounting structure schematic diagram of the present invention.
In figure:1st, core pipe, 2, spilled water hole, 3, steel wire rope, 4, protection cap, 5, lay one's hand on lid, 6, reinforcement, 7, clamp.
Embodiment
As depicted in figs. 1 and 2, a kind of pit shaft spilled water hole guard method, including lid 5 is laid one's hand on, lay one's hand on lid 5 and letting out for pit shaft is completely covered Water hole 2;The upper surface for laying one's hand on lid 5 is provided with protection cap 4;The center for laying one's hand on lid 5 and protection cap 4 is provided with preformed hole, is set in preformed hole There is core pipe 1, lay one's hand on and be uniformly provided with reinforcement 6 in the core pipe 1 of the lower section of lid 5;The upper end of core pipe 1 is provided with upper end cover, the lower end of core pipe 1 Bottom end cover is installed, a steel wire rope 3 is passed through core pipe from upper and lower end cap, and clamp is equipped with the steel wire rope outside upper and lower end cap 7。
By taking Tang Kou coal industrys Co., Ltd south downcast project as an example, spilled water hole is Φ 325X12mm.Described lid of laying one's hand on is Circle, made using δ 30mm × Φ 350mm steel plate;Described protection cap is circular, δ 50mm × Φ 330mm steel plate;Institute The a diameter of 159mm for the preformed hole stated;Described reinforcement uses length 400mm, thickness 30mm steel plate, described reinforcement Muscle has four, is welded in core pipe, using two-sided welding, improves welding quality, welding uses 506 welding rods.Described core pipe is adopted With diameter 159mm, length is 9m drill collar.Steel wire rope uses Φ 30mm steel wire ropes.Clamp uses ingot card, convenient operation.
Present invention installation is as shown in figure 3, spilled water hole protection process is as follows:
