Description
Technical Field
The invention belongs to the technical field of waste rock damming in mine tailing ponds, and particularly relates to a method for damming waste rocks on an earth discharging machine.
Background
The tailing pond damming can be divided into tailing accumulation damming and waste rock damming according to the selected damming material; the method can be divided into an upstream dam piling method, a downstream dam piling method, a middle line dam piling method, a high-concentration tailing dam piling method and a reservoir type tailing dam piling method according to the dam piling form; the method can be divided into a permeable dam and a non-permeable dam according to whether the water is permeable or not. The tailing stacking dam formed by adopting the tailing cyclone for grading and hydraulic stacking is a common damming method in the industry at present and has high economical efficiency. However, according to the practical experience of the domestic tailing damming engineering, the particle size distribution of the tailing sand for damming by using the tailing sand does not have the following characteristics:
the average particle size dp of the tailings is less than 30 μm;
high content of 19 μm, generally >50%;
the content of +74 μm is small, generally less than 10%;
the content of the grain diameter +37 mu m for damming is less than or equal to 30 percent
The tai-yuanjia-village iron ore is used as the largest domestic open-air iron mine at present, because the iron mineral is fine in embedded granularity, the content of +74 mu m in the fine ground tailings is only 7.25%, and the mechanical property and the permeability of the tailings do not meet the requirement on dam building safety, a waste rock dam building process is adopted during design, the waste rock is derived from waste rock stripped from a mining field, and the average transport distance of the waste rock is 7km. The automobile hauls the barren rock from the stope and fills the tailing dam body by layers, the transportation cost is high, and the economy is poor. Particularly, the length of the dam body is continuously increased along with the gradual rise of the tailing dam in the later period, the rock quantity and waste rock cost required by damming are continuously increased, and the waste rock quantity required by damming in each period is shown in table 1. In view of this, it is urgent to develop a method for reducing the construction cost of waste rock damming.

Detailed Description
In order that the invention may be more fully understood, reference will now be made to the following description. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Different from a single automobile development transportation mode, the invention adopts an automobile-semi-mobile crushing-sealing-tape machine combined development transportation mode to build the waste rock dam, and provides a method for stacking the waste rock dam body by utilizing the upper discharge function of a dumping machine, which specifically comprises the following steps: the first mode is that the dumping machine directly arranges the materials to build the dam, and the second mode is that the dumping machine discharges materials nearby, and the digging machine and the automobile are used for secondary transportation to fill the dam body.
Furthermore, the operation modes of directly piling up the dam body on the upper row of the dumping plough comprise a first upper row operation mode and a second upper row operation mode; the first upward-discharging operation mode is that the dumping machine is positioned between the upstream of the belt conveyor and the downstream of the dam body, the dumping machine is followed to perform upward discharging and damming and rock discharging, and the rock discharging direction of the dumping machine is integrally consistent with the development direction of the dam body (see fig. 1 and 2); the second upward-discharging operation mode is that the soil discharging machine is positioned at the downstream of the adhesive tape machine, and the discharging arm rotates and penetrates through the upper part of the adhesive tape machine to perform upward damming and rock discharging (see fig. 4).
The method for damming up the waste rocks on the dumping device provided by the invention is explained in detail by combining with a specific example. The Tai-Yuan-Yuanjia-village iron ore adopts a waste rock downstream type damming process, the tailing pond and the dump are adjacently arranged, and the dump is located downstream of the tailing dam. The initial dam is built and put into service in 8 months in 2012, and the fourth-stage dam (the height of the top of the dam is 1690 m) is built in 2018. The rubber belt rock dumping system of the footwall dumping yard is built and put into use in 2017, a rectangular dumping process is adopted, and the tail section P01 rubber belt machine is arranged in parallel to the axis of the dam. Taking dam building of the four-stage dam of the iron ore tailings of the tai-yuan village as an example, specific examples are as follows:
reference example
The traditional single-vehicle direct-discharging waste rock mode is adopted to build the four-stage dam, 630 thousands of rocks need to be discarded, the distance of vehicle transportation is 7km, and the transportation cost required by rock building of the four-stage dam is 4021.81 ten thousand yuan.
Examples
A method for piling a four-stage dam by adopting a waste rock discharging method of a dumping machine comprises the following steps:
step 1: adopting a dumping machine to carry out waste stone upper-discharging damming according to an upper-discharging operation mode I, stopping damming when the upper-discharging height of the dumping machine reaches 12m, and referring to a formed dam body outline in figure 6, wherein the concrete dumping process parameters and the safety distance in table 2;
step 2: adopting a dumping machine to continue to perform dumping waste rock damming according to the second dumping operation mode, stopping damming when the height of the dumping machine reaches 12m, and referring to a figure 7 for the profile of a formed dam body, wherein specific dumping process parameters and safe distances are referred to a table 2;
and step 3: the second dumping mode is adopted for the piling work exceeding the upper dumping height or the maximum dumping width of the dumping machine, namely, the dumping machine is adopted for blanking nearby, and then the excavator and the automobile are used for secondary dumping, so that a four-stage dam is finally formed (see fig. 8).
Compared with the reference example, about 41% of rock quantity required by the four-stage dam waste rock damming can be directly abandoned by an earth discharging machine in an upward-discharging operation mode, 18% of rock quantity can be directly abandoned by an earth discharging machine in an upward-discharging operation mode, and the rest 41% of rock quantity is completed by an excavator and an automobile in a reverse stacking mode.
The rock transportation cost in the process of building the dam by arranging the waste rocks on the dumping machine can be reduced by 1920.2 ten thousand yuan, and the cost reduction rate is 47.73%. Compared with the traditional single-vehicle direct-discharging waste rock damming construction method, the waste rock damming rock transportation cost is reduced by nearly half.
