Mining life-rescuing system

Abstract

The invention provides a mining life-rescuing system. By adoption of the life-rescuing system, when accidents such as collapse and water seepage, and disasters happen to caves during deep excavation construction of mines or tunnels by workers, the human mortality can be decreased, and the rescue waiting time can be prolonged for trapped workers. The mining life-rescuing system comprises a life-rescuing pipe and a rescue feeding device. The life-rescuing pipe is arranged in a mine in advance; and when a mine disaster accident occurs, the rescue feeding device and the life-rescuing pipe are connected by rescue workers so that lamplight, water, liquid food and fresh air can be supplied to miners trapped in the mine for maintaining the lives of the trapped miners, and the rescue workers can get in touch with and keep communicating with the trapped miners through the life-rescuing pipe, so that information such as the specific positions and the casualty condition of the trapped miners can be known in time, a rescue team can be assisted in making an efficient rescue scheme, and metal appeasing and self-rescue guiding can be conducted for the trapped miners through the life-rescuing pipe.

Description

[0001] Technical field [0002] The present invention relates to a life rescue system, especially a kind of deep excavation operation for workers in mines or tunnels, to prevent caves from collapsing, flooding and other accidents and disasters, reduce personnel deaths, and prolong the life time of trapped people waiting for rescue. A mine life rescue system. Background technique [0003] At present, our country is the largest coal producer and consumer in the world. Last year, the world's coal output was 7.9 billion tons, and our country's was 3.87 billion tons, nearly half of it. Currently we have 11,000 coal mines with 5.8 million coal miners. If there are three shifts, there are nearly two million people working in the underground tunnels every moment, so the problem of safety production is a long-standing problem in coal mines, and it is also the top priority of safe production in the whole country. Besides, there are many other mines with a population of 100,000. It is ...

Problems solved by technology

If there are three shifts, there are nearly two million people working in the underground tunnels every moment, so the problem of safety production is a long-standing problem in coal mines, and it is also the top priority of safety production in the whole country. In addition, there are many other mines with a population of 100,000. It is difficult to count the number of workers in various mines. Historically, the death rate of mine workers caused by accidents such as mine collapse or flooding is also very high. According to statistics, nearly ten The total number of deaths in national coal mine safety accidents in 2018 was 47,902, with an average annual death rate of 4,790. When accidents such as landslides occurred in the mines, the surviving workers who were trapped in the depths of the mines had to wait for rescue from the outside world in darkness and despair. When the buried miners waited for rescue for a long time, the miners died due to lack of food and water. Some governments mandated that the mines must be set up at a certain distance to store rescue supplies. There are basic rescue supplies such as food and water inside. It often takes a long time, and the specific location and situation of the buried workers are not known, which can easily affect the speed of rescue and the formulation of a rescue plan, delaying the speed of rescue, and if the food storage materials are not supervised and regularly replaced and put in dark and humid It is easy to store out of date in the mines, causing the miners to get sick and poisoned by eating spoiled food when they are trapped, which will cause panic. Therefore, this method of prolonging the lives of trapped people and gaining time for rescue is also inappropriate. It is necessary to invent A more scientific and effective new life rescue system that can prolong the lives of trapped people and buy time for rescue
