(1) The cost of tunneling is low. The cost per metre of tunneling is much lower than that of the shaft, and the maintenance cost is low. The installation facilities in Pingyi are simple, unlike steel shafts, such as steel (wood) beams, tanks, sound and light signals, etc., and there is no need for special pedestrians and corresponding pedestrian production capacity. The total cost (including excavation, masonry and installation costs) is still less than half of the vertical shaft, and the amount of infrastructure construction when using Pingshuo is small; Pingyi does not require complicated downhole yards and complex auxiliary facilities (such as rocking tables) like shafts. Or pallets, cans, etc.); the flat mouth is simple to set up, no need for derricks and hoisting machine rooms; flat rafts do not require as much heavy equipment as shafts, so the investment cost is low.

(2) Pingyi facilities are easy to manage and have good construction conditions. The speed of ploughing is much faster than that of the shaft. Especially in today's rapid progress in the level of mechanization, such as the use of rock drilling rigs and vertical rock-loading machines, the construction conditions and roadway speeds of the tunneling work have been greatly improved, even for large-section roadway excavation. The speed is also unmatched by the shaft (under the same conditions, the laneway speed is 2 to 3 times the shaft construction speed). Therefore, mines developed with Pingyi have short infrastructure time and can be put into production early, which is effective early.

(3) The drainage cost of Pingyi is low. The flat drainage is discharged by the flat drainage ditch (and the shaft needs special drainage facilities), which greatly reduces the drainage cost of the mine.

(4) The cost of transportation equipment is low. In terms of the price of the Ñ„2000 double-barrel winch, the cost is two to three times that of the equivalent transport equipment.

(5) The transportation cost of Pingyi is low. The transportation cost of flat ore per unit length is much lower than that of the shaft, which is generally only 1/3 of the cost.

(6) It is easy to ventilate in the flat (such as a single flat development, in small mines, often with natural ventilation to meet production needs), and simple. Flat ventilation costs (distributed by per ton of ore) are lower than shaft development.

(7) Pingyi production is safe and reliable, transportation is far greater than the transportation capacity of the shaft, and it is easy to manage. Unlike the shaft lifting, there are often accidents such as falling tanks and mine car falling wells.

Because of the development of Pingyi has more significant advantages. Therefore, as far as conditions permit, it should be used as much as possible.

Conveying Equipment Series

The Conveying Equipment Series is a collection of machines designed to transport materials from one place to another. These machines are used in a variety of industries, including manufacturing, mining, agriculture, and construction. They are essential for moving materials efficiently and quickly, reducing labor costs, and improving productivity.

One of the most common types of conveying equipment is the conveyor belt. This machine consists of a belt that moves continuously, carrying materials from one end to the other. Conveyor belts are used to transport a wide range of materials, including grains, coal, rocks, and chemicals. They are available in different sizes and configurations, depending on the specific needs of the industry.

Another type of conveying equipment is the bucket elevator. This machine consists of a series of buckets attached to a chain or belt. The buckets are used to scoop up materials from one level and transport them to another level. Bucket elevators are commonly used in the agricultural industry to transport grain and other crops.

Screw conveyors are another type of conveying equipment. These machines consist of a rotating screw that moves materials along a trough or tube. Screw conveyors are used to transport bulk materials such as grain, cement, and chemicals. They are commonly used in the food processing industry for transporting ingredients and finished products.

Pneumatic conveying systems are also commonly used in many industries. These systems use air pressure to move materials through pipes or tubes. Pneumatic conveying systems are often used in the chemical industry to transport powders and other materials that are difficult to handle with other types of conveying equipment.

In addition to these types of conveying equipment, there are many other machines available for transporting materials. Some of these include belt conveyors, roller conveyors, vibrating conveyors, and chain conveyors. Each of these machines has its own advantages and disadvantages, depending on the specific needs of the industry.

Overall, the Conveying Equipment Series is an essential collection of machines for many industries. These machines are designed to move materials efficiently and quickly, reducing labor costs and improving productivity. With so many different types of conveying equipment available, it is important for industries to choose the right machine for their specific needs.
