What does horse racing mean for a miner? This is a small miner's lantern that can light up the way while working. The device is being improved year by year. Modern headlights are compact, simple and comfortable.
Where did the name come from
The name "horse racing" came to us from the profession of workers who accompanied horse-drawn haulage trains underground. Konogons carried a lamp designed for mines. It was located on the band of a headdress or was attached to a horse harness.
The first lamps functioned on the basis of surapa oil or other cruciferous plants. They were explosive. The flame of the lamp was not blocked by anything. Not for nothing that many workers called the miner's lantern horse racing “God help.”
Then the profession of a person carrying a lamp arises. To create lighting, it was necessary to hang a lot of such devices.
Who invented the first lantern
The first mining lantern was invented by the Englishman Humphrey Davy in 1815. It functioned on a kerosene basis. Devi was the developer of nitrous oxide, which is widely used in medicine even today. For the advent of the deviceThe Queen of England awarded the inventor the title of Baron. The lantern quickly spread to Germany and then to Russia.
The lamp helped save many lives of miners. With the device, it was possible to descend into the mine, which contained methane. The flame was not in contact with the gas. This explains the lack of explosions.
Before the lantern, miners took a canary with them. As long as the bird sang, coal mining did not pose any danger, and as soon as it stopped, work should have been stopped, since the silence of the bird indicated the appearance of methane.
What the first lamp looked like
The lamp was a small metal structure filled with oil. If the device got into the gaseous environment, the lamp burned only from the inside. The internal space was limited by a grid.
The Wolf lamp, which functioned on the basis of gasoline, became widespread. The miners called her "the benefactor." The weight of such a device was 1 kg, and the gas consumption rate per shift was 0.17 pounds.
As the years passed, the improvement of the design of the lamp did not stop. Yet they remained underpowered and not entirely comfortable.
Acetylene lamp
The carbide or acetylene miner's lantern became a model of a new generation of horse racing. It appeared at the end of the 19th century. The source of light here is a burning gas - acetylene, which was released during the interaction of water and calcium carbide. It is placed in a closed tank in the lower case.lamps.
Such lamps brought more convenience, as they could be mounted on the helmets of the miners. But the designs had a big minus: the flame in them was open. Therefore, where methane was present, the Wolf lamp continued to be used.
Lamps based on electricity
The lamps on the flame were replaced by electric lamps. Mining lamps powered by batteries appeared in 1930. The modern look of horse racing was received only in the middle of the last century. They were produced in Ukraine (Kharkov plant "Light of a Miner"). Today, the factory produces completely new models of flashlights that do not resemble the old ones.
Modern models
Innovative models are smart. They are made of high-strength anti-shock material and have two modes: working and emergency (with low power consumption).
Lamps do not explode and bring comfort to the work of miners. Suitable when working in mines of any category, which are dangerous with gas and dust. Lanterns are able to illuminate the space continuously for 10 hours. Built-in electronic devices can ensure the complete safety of the lamp and control the composition of the mine atmosphere.
LED mining lights
Waterproof and dustproof LED mining lantern attached to the helmet. It is used not only by miners, but also by people involved in mountaineering, hunting, fishing.
The LED miner's flashlight is very convenient, as it makes a person's hands free and can illuminate the place where the person's gaze is directed. The device functions even in conditions of increased extremeness.
The mining LED lantern will last a very long time. Damage to the device is reduced to zero even with a strong fall or ingress of moisture or dust into the case.
Review of some modern models
It should be noted that there are a lot of models of mining lights. This article only lists three models.
Ekoton 6 domestic miner's lantern is intended for use as a wearable lighting device.
The miner's light set includes a power cassette, a five-wire cord, a head light and a charging adapter. The base of the product is plastic. The housing contains a powerful high-power LED module. The lamp is turned on with a button, charged using an adapter or a special station.
The SGD-5M.05 lamp is designed for individual lighting in the mine. The basis of the device is a battery pack and a headlight, which are interconnected by means of a flexible two-wire wire. The battery pack case is equipped with belt clips. Under the cover is a fuse that protects electrical circuits from short circuits. On the body there are plugs for pouring electrolyte. The cover and headlight are made of high-strength plastic. The case is equipped with a switch, with which the operating mode is selected (working or emergency), as well as a charging unit, through which the battery is connected tocharger.
Head model of mining lamp NGR 06-4-003.01. Р.05. The model is non-explosive. Designed for custom lighting. It is equipped with a radio signaling device of one of the systems responsible for safety. Radio signaling devices provide a telephone call, notification of an accident, as well as the search for miners in case of an emergency. The flashlight is equipped with a sealed rechargeable battery.
How to charge a mining lantern
Many people are wondering how to charge a mining lantern?
Modern mining lights in their design contain blocks that operate from batteries. They are of three varieties. Some require electrolyte replenishment, others do not. Blocks that need to be flooded are not as sensitive to discharge / charge mode.
Instructions
How to charge a mining lantern, instructions are given in this article.
- If you are the owner of a modern flashlight model, then when the voltage drops, it will start flashing. In the absence of a signaling system, find out what luminous intensity the device has at 3.0 V. This critical moment should be tracked and the flashlight battery charged. Charging should not be less than 3.0V and more than 4.8V, otherwise the flashlight will swell due to water decomposition. If you are using a factory charger, it will automatically select the correct action. When the voltage is too highthe emergency system will go off.
- When charging, the current should be 1.08A or slightly less. In this case, it will take more time to charge. Charging can be done even with an indicator of 0.92 A. A current greater than 1.08 A is undesirable. Tension should be kept under control. It should be from 3.8 to 5.4 V. If the indicator is lower, then the flashlight simply will not charge, if it is higher, then parallel decomposition of water will occur.
- Do not make mistakes in polarity, otherwise you risk damaging the unit. For this purpose, marks with "+" and "-" signs should be made on the charger.
- Contacts are located in the head office. You should find a metal head with a screwed washer. It is located 4 cm from the place where the cord is connected. There is also a negative side. The positive is located in the recess of the metal holder.
- In the recess there is a sleeve with a slot, and under the sleeve there is a contact. You need to strip him. To this end, the sleeve is rotated around the axis by 180 degrees until it becomes clear that a bare contact is visible through the slot. Flashlight batteries should be connected to the charger. For this purpose, the power supply of the flashlight is opened.
- Do not leave the charger on for more than 13 hours. Otherwise, it will start discharging automatically.
- If you charge the flashlight with a homemade charger, then the process should be monitored with a voltammeter
These are the main points that explainhow to charge a mining lantern.

How to charge a mining lantern at home?
For this purpose, an electrolyte is purchased in a car shop, which is diluted in the required proportion. The density of a substance can be checked using a "pear" made from a dropper. One night is enough to recharge.
After the lantern, an alkaline mining lantern, is charged, the electrolyte is drained into a glass container and tightly closed with a cork.
This do-it-yourself mining lantern charger requires careful handling, as the electrolyte is capable of burning through almost anything that gets in.
