Abstract
The invention relates to an underground hole drilling location ruler and a quick orientation method for hole drilling, which is characterized in that a right-angle transparent triangular rule; one right-angle side of the triangular rule is 0 degree, and the other right-angle side is 90 degrees; the sloping side of the triangular rule is provided with scale from 0 degree to 90 degrees; in the quick orientation method for hole drilling, a set of datum lines which are vertical to the middle line of a lane on a horizontal projection plane are arranged in the lane or a roadway wall drilling field; the height of the datum lines is regulated, so that the lines intersect with a drill pipe at an intersection point on the same horizontal plane; the right-angle top point of the hole drilling location ruler is coincident with the intersection point: one right-angle side leans to the drill pipe, and the angles formed between the other right-angle side and the datum lines are the relative location angles for hole drilling. The invention is applicable in quick orientation for underground coal mine hole drilling and drill hole acceptance; the underground hole drilling location ruler is simple to be manufactured, with convenient operation in quick orientation for hole drilling and the orientation error less than 0.5 degree.
Description
Technical field
The present invention relates to the down-hole drilling orientation method in the coal mine operation.
Background technology
Gas pumping is one of important technique measure of the coal mine gas comprehensive regulation, particularly low air permeability coal seam highly gassy mine and coal and gas outburst mine, and when adopting along layer long drilled holes with the layer-through drilling mash gas extraction, a drill site often will arrange that more than 100 is holed.For a long time, down-hole drilling is directed checks and accepts to adopt methods such as circumferentor, transit and calculating with boring more, owing to receive the influence of tunnel steel lining material and rig, compass unwrapping wire method error is bigger; Transit and computing method need on ground, a large amount of calculating is carried out in the down-hole and measure setting-out work, and be not only loaded down with trivial details but also be awkward.
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology weak point, a kind of down-hole drilling direction ruler simple and easy to operate, that precision is higher and boring fast orienting method made being provided.
Technical solution problem of the present invention adopts following technical scheme:
The design feature of down-hole drilling direction ruler of the present invention is that the transparent set square in right angle is set, and is 0 degree with a right-angle side of said set square, and another right-angle side is 90 jiaos, and the angle index of 0-90 is set on the hypotenuse of said set square.
The design feature of down-hole drilling direction ruler of the present invention is that said transparent set square is that transparent organic glass with 3～5mm is a material, and the angle index of 0-90 is to be scale unit with 1 degree on its hypotenuse.
The characteristics of down-hole drilling fast orienting method of the present invention are in the tunnel or lane group drill site is established one group of reference line vertical with the tunnel center line on horizontal plane; Regulate said reference line height and drilling rod and on same horizontal plane, intersect at an intersection point; The summit, right angle of bore direction chi is overlapped with said intersection point; The one right-angle side drilling rod that reclines, the angle of another right-angle side and reference line is the boring relative bearing.
Compare with orientation method with the directed utensil of existing boring, beneficial effect of the present invention is embodied in:
1, precision is high, and error has been avoided the bigger deviation of the directed generation of compass less than 0.5 °;
2, make simple, easy to operate, save time, using a horizontal vertical line can be all boring orientations in the drill site, has shortened boring orientation time greatly;
3, save measuring apparatus unwrapping wire and computing method orientation and need do a large amount of calculating and underground survey work;
4, reduce useless hole, improved the boring acceptable quality level greatly;
Description of drawings
Fig. 1 is a direction ruler structural representation of the present invention.
Fig. 2 is the present invention's orientation principle sketch map of holing.
Label among the figure: 1 tunnel outline line, 2 rigs, 3 drilling rods, 4 bore direction chis, 5 tunnel center lines, 6 reference lines, 7 relative bearings.
Below, the present invention is described further in conjunction with accompanying drawing through the specific embodiment.
The specific embodiment
The bore direction chi is made: adopt the thick transparent organic glass of 3～5mm; Make the drawing square of 40～50 centimetres of the right angle length of sides; Utilize computer CAD drawing; An angle of 90 degrees is divided into 90 angular units, prints drawing and stick on the ready-made isosceles drawing square, scale is drawn on the hypotenuse of drawing square.
Down-hole drilling slewing: before the boring perforate;, drill site finishes position of opening by design on meeting head on section; Utilize construction tunnel center line 5; Meet head in the tunnel or lane group drill site apart from 1～3 meter of position of opening (before or after the rig), establish one group of reference line vertical with the tunnel center line on horizontal plane 6, reference line 6 two ends are fixed on that tunnel two is helped and exceed about 0.5 meter than rig 2 with surveying to follow closely; Behind the firm rig 2; Connect drilling rod 3, with the drill bit position of opening, height and the drilling rod 3 of regulating reference line 6 intersect on same horizontal plane; Bore direction chi 4 is placed the place ahead of reference line 6; The summit, right angle overlaps with intersection point, a right-angle side recline drilling rod 3 and horizontal positioned, and the angle that records another right-angle side and reference line 6 is the relative bearing 7 of boring and tunnel center line; If relative bearing of surveying 7 and different design, adjustment rig 2 orientation make the relative bearing 7 that records be consistent with the design azimuth and promptly accomplish the orientation of this boring.
When using, the present invention should note:
