Description
Technical Field
The invention relates to the field of mine dumping grounds, in particular to an operation method of a dumping machine.
Background
In the field of mine dumping grounds, a proper dumping mode is selected according to different exploiting transportation modes, rock and soil properties, transportation quantity, transportation distance and other factors, wherein the belt-dumping machine mode is suitable for large mines with large transportation quantity, long transportation distance and high transportation altitude difference.
The Yuanjiavillage iron ore is used as the current largest open-pit iron mine with single pit, and the quantity of stripped waste rocks reaches 6380 ten thousand tons every year. The lower-tray dumping ground is designed to adopt an automobile-semi-mobile crushing-belt conveyor combined development transportation mode and a belt-dumping machine dumping mode, the design capacity is 3500 ten thousand tons/year, the hourly capacity is 7650t/h, the operation rate is 52.23%, the belt speed of the belt conveyor is 5.027m/s, and the belt width is 1.8 m. The system adopts a B1800(50+50)9000t/h type dumping machine, the instantaneous rock dumping amount is equivalent to that of a 130 Haoho automobile, the rock dumping strength is very high, and the system belongs to a large rock dumping system with the largest equipment specification and the highest system capacity in China at present.
Because a large amount of fourth-system collapsible non-collapsible loess exists in the region, the average occurrence thickness reaches 19m, the method is limited by the technical problems of weak foundation conditions and easily weathered rock types of the dumping yard, low counterweight of the dumping machine, cross influence of a belt conveyor and the like, and the self stability and the foundation strength of the dumping yard cannot support the safe, continuous and efficient dumping operation of the dumping machine all the time.
Disclosure of Invention
The invention aims to overcome the defects that the self balance weight of the dumping plough is too low and the base of the dumping yard is soft, improve the strength of the base of the dumping yard and the operation method of steps, and further realize safe, continuous and efficient dumping operation of the dumping plough.
The invention provides an operation method of a dumping plough, aiming at improving the base strength and the strength stability of the dumping yard and realizing the safe and efficient dumping operation of the dumping plough.
The operation method of the dumping machine is characterized by comprising the following steps:
(1) adopting an automobile dumping preloading platform 3-6 months ahead of time to carry out back pressure on the slope toe of the rubber belt rock-discharging step, and controlling the height of the rock-discharging platform stage of the dumping machine to be no more than 80 m;
(2) when the dumping machine is used for dumping, firstly dumping the slope toe, wherein the primary dumping height is not more than 1/2 of the height of the integral dumping section, and after the interval is 35d, dumping for the second time is started, and the dumping for the height of the integral step is finished at least 2 times in a reciprocating way;
(3) after the adhesive tape machine is moved each time, the upper row of tissues is 45d, so that the lower row of steps at the outer side has time for consolidation and settlement; the dumping machine is firstly dumped at the upstream side of the adhesive tape machine during the upper dumping, the stacking height is 12m, the distance between the slope foot of the upper dumping step and the track of the adhesive tape machine is not less than 30m, and the walking requirement of the dumping machine during the return is ensured; the dumping machine finishes dumping on the upstream side of the adhesive tape machine and winds the end part of a head wheel of the adhesive tape machine to the downstream side of the adhesive tape machine, the dumping is carried out simultaneously for the lower-discharging operation, a dumping arm spans the adhesive tape machine for the upper-discharging operation, and the distance between a slope foot of an upper-discharging step and the adhesive tape machine is not less than 10 m;
(4) because the balance weight is arranged on the dumping machine below the material receiving arm, in order to avoid collision between the balance weight and the adhesive tape machine in the rotation process of the dumping machine, the dumping machine distributes materials at the front end of the operation in advance, the dumping machine is assisted to be pushed flat and lifted to the standing position of the dumping machine, and the height difference between the position of the dumping machine and the position of the adhesive tape machine parallel to the dumping machine is + 0.5-1 m.
The invention improves the operation efficiency of the dumping machine of the large-scale rubber belt dumping system, and the essential safety and reliability of the dumping site are greatly improved.
Detailed Description
Comparative example: the traditional operation method of the dumping plough is influenced by the soft foundation condition of the dumping site and the type of easily weathered rocks, the slope shoulder differential settlement representing the self stability of the dumping site is adopted, and the settlement amount 1d after the construction reaches 6.5 percent (about 5.2 m) of the height of the whole step.
Example 1: compared with a comparative example, differential settlement of the slope shoulder of the waste dump is obviously reduced by piling up the toe back pressure platform, and the settlement amount of 1d after construction is 1.9-2.4% (1.5-2 m) of the height of the whole step.
When the dumping machine is used for dumping, the slope toe is preferentially discarded, the dumping is carried out for more than 2 times to form an integral dumping step, and the differential settlement amount of the slope shoulder of the dumping step is only about 1% of the height of the integral dumping section after work and is 800mm after work for 1 d.
The adhesive tape machine of the invention is arranged in the upper row preferentially after each transfer, so that the operation steps in the lower row have a certain time for consolidation and settlement, the interval time is not less than 45d, and the differential settlement amount of the slope shoulder of the soil discharging step is only about 500mm after 1 d.
The invention adopts the dumping machine produced by Taiyuan heavy industry Co., Ltd, and the elevation of the standing position of the dumping machine is 0.5-1 m higher than that of the adhesive tape machine. The rock discharging operation of the dumping plough is not affected when rotating, and the dumping plough can realize continuous reading and material carrying operation.
