Abstract
Description
Technical Field
[0001] This invention belongs to the field of waste disposal technology in mining engineering, and relates to waste disposal operations, specifically a convenient method for measuring and adjusting the slope of a waste disposal site. Background Technology
[0002] In the production of dumping and rock removal operations by truck at the dump site, it is necessary to measure the reverse slope parameters of the dump site and verify whether the dumping slope meets the requirements of the "Safety Regulations for Metal and Non-metal Mines" (GB16423-2020) which stipulates that "platforms in hillside dump sites should be equipped with a reverse slope of 2% to 5%". The dumping operation should be guided according to the actual slope.
[0003] To ensure that the spoil disposal process meets standards, previously, professional surveyors used specialized surveying equipment (total stations or GPS instruments) to periodically measure and map the slope of the spoil disposal site, resulting in a low measurement frequency. In refined spoil disposal production, the slope of the spoil disposal site needs to be measured daily, leading to a higher measurement frequency. However, due to insufficient surveying personnel and instruments, the high-frequency measurement of spoil disposal slope parameters cannot be met for refined production. This frequently affects the quality assessment of truck spoil disposal operations and hinders timely verification of spoil disposal slope parameters, ultimately impacting the compliance of the truck spoil disposal process. Summary of the Invention
[0004] The purpose of this invention is to provide a convenient method for measuring and adjusting the slope of a spoil heap, thereby achieving refined quality control of spoil heap production operations, facilitating spoil heap production management and operator operation, and enabling timely inspection of spoil heap slope parameters to improve the quality of truck spoil heap operations.
[0005] The technical solution adopted by the present invention to achieve the above objectives is as follows: A convenient method for measuring and adjusting the slope of a spoil heap includes: S1. Measure the slope between two points before and after the direction of the spoil disposal site: S11. A measuring rod is vertically fixed at each of the front and rear points. A horizontal short rod is set at the same height in the middle of each measuring rod. A tape measure is straightened and fixed between the two horizontal short rods. S12. Using the zero point and scale of the measuring tape as a reference, check the accuracy of the position of the measuring tape at the center of the horizontal short rod at the two points before and after passing through the measuring rod. S13. Place the bottom edge of the electronic slope meter parallel to the straightened tape measure and read the electronic slope meter reading. This reading is the slope data Vi between the two base points on the ground. S14. Repeat S13 to check for errors in the numbers. Compare the two sets of data. If the difference between the two sets of data is less than 1%, take the average value V of the two sets of data. S2. Slope adjustment logic between two points before and after the spoil disposal direction at the spoil heap: When 2%≤V≤5%, the slope of the current spoil disposal site is acceptable and no adjustment is required. When V < 2%, the slope of the current spoil heap is substandard and needs adjustment. The adjustment amount is... △H=(2%-V)*L, where L is the distance between the front and rear measuring rods. The adjustment direction is to raise the base point in the forward direction and to adjust the slope in the current soil discharge direction to meet the requirements. When adjusting the slope, mark the slope adjustment height at the base point in the forward direction to guide the slope adjustment operation. When V > 5%, the slope of the current spoil heap is substandard and needs adjustment. The adjustment amount is... △H=(V-5%)*L, where L is the distance between the front and rear measuring rods. The adjustment direction is to lower the base point in the forward direction to lower the current soil discharge direction to make the slope qualified. When lowering, mark the lowering height at the base point in the forward direction to guide the slope reduction operation. S3. Measurement and adjustment of the slope of the entire spoil disposal platform in the direction of spoil disposal; S31. Following the steps in S1, measure the slope Vi (i=1, 2, ..., n) of the spoil disposal platform along the spoil disposal direction at 100-meter intervals. S32. Following the method in S2, adjust the slope between the two points before and after the dumping direction of each dumping site, and record the slope measurement and adjustment of each dumping direction of the dumping platform.
[0006] Furthermore, the probe is made of Φ8mm steel bar and includes a probe rod and a probe tail. The probe rod is painted with alternating red and yellow colors at 100mm intervals. A horizontal short rod is set at 500mm of the rod body, and the probe tail is set in a ring shape.
[0007] Furthermore, in S3, the slope of the dumping direction is measured every 20 meters during the dumping operation to ensure that the dumping slope is within acceptable limits.
[0008] The beneficial effects of this invention are: This invention provides support points for the measuring tape and baseline points for slope measurement using a measuring rod. The electronic slope meter uses the measuring tape as the baseline, and the slope measured on the tape is the slope between the two baseline points of the spoil heap. Simultaneously, based on the measured slope and spoil heap slope adjustment logic, the current spoil heap direction can be adjusted or lowered. This invention allows on-site workers to determine the spoil heap slope direction with the assistance of production management personnel, overcoming the shortcomings of insufficient surveying personnel and instruments. It enables high-frequency measurement of spoil heap slope parameters for precise spoil heap production, making it simple to determine whether the spoil heap slope direction is acceptable on-site, thus allowing for timely adjustment of unacceptable slopes and improving the quality of spoil heap operations.

[0010] The present invention will be further described below with reference to the embodiments and accompanying drawings: A convenient method for measuring and adjusting the slope of a spoil heap includes: S1. Measure the slope between two points before and after the dumping direction at the spoil heap, such as... Figure 1 As shown, taking the example of three workers cooperating to measure the slope between two points 10m apart: S11. Operator 1 (7) and Operator 2 (8) respectively erect a measuring rod vertically at two points before and after the dumping direction of the dump site. Operator 1 (7) and Operator 2 (8) straighten a tape measure 4 and fix it between two horizontal short rods 3 at the same height in the middle of the two measuring rods. Operator 1 (7) fixes the zero point of the tape measure 4 through the center of the horizontal short rod 3. Operator 2 (8) fixes the 10m scale line of the tape measure 4 through the center of the horizontal short rod 3. S12, Operator 39 directs from the center, and uses the zero point and 10m scale of the tape measure 4 as a reference to check the accuracy of the center position of the tape measure 4 passing through the horizontal short rod 3 of the measuring rod at the two points before and after. S13. After the operator checks and confirms, the bottom edge of the electronic slope meter 5 is brought close to the straightened tape measure 4. The baseline 6 formed by the tape measure 4 is used to read the reading of the electronic slope meter 5. This reading is the slope data Vi between the two base points on the ground. S14. Repeat step S13 to check for errors in the numbers. Compare the two sets of data. If the difference between the two sets of data is less than 1%, take the average value V of the two sets of data. S2. Adjust the slope between two points before and after the dumping direction at the spoil heap. The adjustment logic is as follows: Figure 2 The table content is shown below: When 2%≤V≤5%, the slope of the current spoil disposal site is acceptable and no adjustment is required. When V < 2%, the slope of the current spoil heap is substandard and needs adjustment. The adjustment amount is... △H=(2%-V)*L, where L is the distance between the front and rear measuring rods, which is 10m at this time. The adjustment direction is to raise the base point in the forward direction and to make the slope qualified for the current soil discharge direction. When making the base point, mark the height of the base point in the forward direction to guide the base point operation. When V > 5%, the slope of the current spoil heap is substandard and needs adjustment. The adjustment amount is... △H=(V-5%)*L, where L is the distance between the front and rear measuring rods, which is 10m at this time. The adjustment direction is to lower the base point in the forward direction to lower the current soil discharge direction to make the slope qualified. When lowering, mark the lowering height at the base point in the forward direction to guide the slope reduction operation. S3. Measurement and adjustment of the slope of the entire spoil disposal platform in the direction of spoil disposal; S31. Following the steps in S1, measure the slope Vi (i=1, 2, ..., n) of the spoil disposal platform along the spoil disposal direction at 100-meter intervals. S32. Following the method in S2, adjust the slope between the two points before and after the dumping direction of each dumping site, and record the slope measurement and adjustment of each dumping direction of the dumping platform.
[0011] In addition, the slope of the dumping direction is measured every 20 meters of the dumping operation to ensure that the dumping slope is up to standard.
[0012] The probe is made of Φ8mm steel bar, such as... Figure 3 As shown, it includes a measuring rod 1 and a probe tail 2. The measuring rod 1 is painted with alternating red and yellow colors at 100mm intervals. A horizontal short rod 3 is set at 500mm of the rod. The probe tail 2 is set in a ring shape.
[0013] The measuring rod 1 can serve as a base point for slope measurement and provide a support point for the measuring tape 4. The red and yellow color intervals of the measuring rod 1 provide the height data of the measuring tape 4 from the ground. When the measuring rod is not in use, it can be suspended by the rod tail 2.
[0014] The measuring tape 4 uses a 30m long measuring tape. When measuring, the measuring tape 4 is straightened and fixed to the horizontal short rod 3 through the measuring pins of the front and rear base points. The measuring tape 4 provides both the distance between the front and rear base points and the baseline 6 for the electronic slope meter 5 to measure the slope.
[0015] The electronic slope meter 5 measures the slope of the baseline 6 formed by the tape measure 4, and the data is the slope between the two points of the spoil heap.
[0016] This embodiment of the method uses a measuring rod, a tape measure 4, and an electronic slope meter 5. Three operators work together to measure the slope between two points before and after the dumping direction of the spoil disposal site. The measured slope data is used as the basis for adjusting the slope of the dumping direction, and adjustment data for the slope of the dumping direction is provided. The calculation of the adjustment data is carried out using a fixed table, which simplifies the calculation and makes it more on-site.
[0017] The method of this invention is characterized by safety, high efficiency, and strong guidance, providing accurate data support for truck dumping operations at spoil heaps, improving the quality of truck dumping operations, and promoting the achievement of standards in truck dumping operation processes.
