Description

The object of the present invention is a method of orienting a submersible survey through one vertical shaft using a non-free plumb, one end of which is fixed at the surveying mark on top of the earth and the other at the survey marker in the mine. On the surface of the earth — an unmounted plummet is pulled away by additional wire, and by a wire, to which, lik to, from, cutting of a not free leg, going to the Mining shark mark on the surface, under a free plumb line. According to the position of the free plumb relative to the height of the non-free plumb at the level of a theodolite installed at the surveyor in the employee, the correcting angle is determined for the transition from the azimuth of the non-free plumb segment to the surface to the azimuth of the non-free plumb segment. mine.

Orientation techniques for the proposed method are illustrated in the drawing, where in FIG. 1 and 2 are given variants of the location of the plumbs in the mine; in FIG. 3 - fastening details of the connecting wire to the

plumb-wire, fig. 4 is a plan view of a support bracket for a non-free plumb; FIG. 5 is a view of the tie strap located in the mine; FIG. 6 is a view of a square for measuring the horizontal projection of a wire rod.

The wire from the winch And lowered with a load into the mine. Also, the wire from the winch is lowered with rpyiz. Then the wire is pulled by the connecting wire BV. Details of the connecting wire are shown in FIG. 3. Rollers I made of wood have the shape of a ciladra. Their diameter is about 4 cm. P - two plates. from roofing iron or aluminum, between which the wire passes. In each plastic there are three holes, two for the rollers and one for the connecting wire. On the sides of the roller, I am fastened with pins. To lay the plumb wire, you need to take out the middle roller. When the wire is driven, the roller should be inserted back and secured with a pin.

In the point L set theodolite. Co-ED points B and G with vertical thread bring the entire system of wires to a position close to the vertical plane passing through the point A & F (phi: H. 1 and 2). This rotation is similar to the actions performed in the usual orientation by a broken plumb line.

At the point D, a bracket that is perpendicular to the plane of the drawing is hammered. Wire D, G, B is put on the shit. On the skoba (fig. 4) / napieaaiHbi with a hacksaw, after approximately 0.4 cm. The staple is positioned so that the cuts are on either side of the wire.

Next, normal weights L, M are suspended. Then, a VM wire is attached to the cord, one end of which passes through the center of the survey marker sign, and on the other there is a collar (Fig. 5), which is connected to the wire BL on which the scale is strengthened. The sperm in the collar is caught through the incision. A non-free plumb that is inserted between the collar wire, as shown in FIG. 5, and then 1 free plumb.

After fixing the cord at the point G on the clamp, perpendicular to the direction of the cord the SAME strengthens the scale with the help of;

Thus, the scale oscillates vm1este with a plumb VM.

At the point Zh, a theodolite is established and produced in the usual way by scale measurements of the position of the BL wire relative to the VM wire.

The position of the VM wire is defined as (the sum of readings along the edges of the wire. The wire of the VM is fixed relative to the scale.

After the production of scale readings, after waiting for the plumbs to calm down sufficiently, the primitive angle IB to the point A. is measured.

After this, the BV projection is measured, which is easiest to do with the help of a square (Fig. 6) with a leg larger than the BV distance, cut from plywood, with a plumb line leading it to a horizontal position.

In order to control and increase

accuracy of the final result, orientation should be done several times. Let us take it is desirable to take the positions of points B, symmetrical with respect to the vertical plane passing through points A and G, and at the same time moving the scale.

To obtain the wire position for the purpose of re-orientation, it is sufficient to shift the wire from one cut to the other.

To transfer the coordinates, it is necessary to measure the distance AB and Ж5 with a tape measure, then AB AB + BV and ЖВ ЖЗЗ БВ.

In the event that the mine is single-winged and it is not possible to arrange cHCTeMiy wires as shown in FIG. 1, but it is possible to locate the first mill in the mine along the landfill, then the located wire will correspond to FIG. 2. In this case, the schematic diagram does not change significantly. In the first variant, the plumb line BL was fixed directly on the running side (mill) -AV, according to the second variant, the free plumb line BL was fixed out of turn.

In order to transfer the directional angle to the mine, it is necessary to determine the angle ABL, which can be imagined as the sum of 180 ° g /.

The order of operation remains the same as in the first embodiment.

Subject and perusal

The method of orienting underground surveys through one vertical shaft using a non-free plumb line, one end of which is fixed at the surveyor’s mark on the surface of the earth, and the other at the surveyor’s mark in the mine and is drawn by additional wire on the surface, which differs from delay or to a segment of a non-free plumb, going to the surveying sign on the noBepxiHOCTH of the earth, hang the free plumb and on the position of the free plumb relative to the plane of the non-free plumb at theodol level one mounted in a mine surveyor sign is determined polravo-screw angle for the transition from a non-free plumb azymuta segment at the ground surface to the non-free plumb azimuth segment in the mine.
