(54) METHOD FOR DETERMINING VOLUMES OF FORCED MOUNTAIN MASS

(57) Essence: includes determining the relief of the working quarry before and after excavation of the rock mass by optical means by determining the partial distances

from the plane parallel to the earth's surface to the working surface of the quarry using laser sensors installed on the arrow of the dragline, determine the partial area, compare the corresponding partial distances of the previous and subsequent measurements, multiply the result of the comparison by the specified partial area and get the partial volumes, summed which receive volumes of excavated rock mass. 2 Il.

The invention relates to earth moving machinery and can be used in earth moving machines, such as excavators.

There are two types of definition of excavator performance, one of which is to determine the weight of the bucket during each excavation cycle, the other by the volume of the excavated rock mass.

The closest to the proposed method is the method of determining the volumes of rock mass removed from the quarry, which includes picking up information about the relief of the pit from the aircraft before and after the mining mass

However, the known method does not allow to determine the volume of the removed rock mass by the dragline excavator. In addition, means of implementing a known method are expensive, since the filming is carried out from an airplane.

The aim of the invention is to extend the functionality by

determination of excavation of rock mass by a dragline excavator

The goal is achieved by determining the relief of the quarry before and after excavation using optical methods in the method of determining the volumes of rock to be removed, while measuring the partial distances from the plane of the boom to the surface of the quarry using laser sensors installed on the boom of the dragline excavator, the partial surface area compares the corresponding parameters of the previous and subsequent measurements, multiplies them by the partial surface area, with the resulting value ate a volume ekskaviruemoy rock mass. The measurement of partial distances allows accelerating the removal of the working relief of the quarry by eliminating the photogrammetric method of obtaining the relief, which requires time to process photographic materials and digitize them.

The proposed method calculates the volume once, while the known method calculates it twice.

FIG. 1 shows the location of the sensor on the dragline excavator, side view; in fig. 2 - the same, top view.

FIG. Figure 1 shows a dragline excavator, on the boom of which a laser sensor 1 is installed, a working distance measurement zone 2, which covers the entire width of the surface being excavated, where a is the scanning angle. FIG. Figure 2 shows the working surface of the quarry, where a) is the angular velocity of rotation of the excavator (passport value).

The method is carried out as follows.

Before measurement, the excavator bucket is fixed by a pull rope near the excavator body. When the excavator rotates around its axis at a speed of about; The laser sensor 1 measures the partial distances to the working surface of the pit over the entire width of the working zone 2.

Thus, having made a complete revolution around the axis, partial distances are obtained over the entire working surface of the quarry.

Then, the rock mass is excavated. After this, the measurement operation is repeated. Measurement results for processing are transferred to a computer that determines the volume of the excavated rock mass.

Claims (1)

Claims The method of determining the volumes of excavated rock mass, including determining the working quarry relief before and after excavating the rock mass by optical means, is characterized in that partial distances from the plane are determined to enhance the functionality by detecting the rock mass excavation by a dragline excavator. , parallel to the earth's surface, to the working surface of the quarry using laser sensors installed on the boom of the dragline excavator, set the partial area, compare The corresponding partial distances of the previous and subsequent measurements, the result of the comparison is multiplied by the specified partial area and receive the partial volumes, summarize them and get the volume of the excavated rock mass.
