Description

Technical Field

[0001] The invention relates to a rapid escape technology for underground space operation in a coal mine, and in particular to a rapid escape equipment and method for underground space operation in a coal mine. Background Art

[0002] The rapid development of the national economy has driven the rapid growth of demand for mining resources. With the continuous improvement of the mechanization and centralization of underground mining production, large modern mines have emerged. Due to the special working environment and complex geological conditions, accidents are prone to occur frequently, the accident spreads quickly, the disaster risk area is large, and the escape route is long, which is not conducive to the safe and rapid escape of underground workers from dangerous areas. At present, the protective equipment for underground space operations mostly involves refuge chambers and escape shelters. These devices store water, food, and compressed oxygen tanks necessary for survival for emergency use by refugees. However, the equipment still has many loopholes: (1) The functional radiation range is limited, and the dispersion of the operating locations of the operators is not taken into account. When a disaster occurs, it is difficult for the farthest operator to retreat to the refuge cabin within the effective time of the respirator; (2) The safety reserve capacity is limited, and it can only accommodate a limited number of people for evacuation within a limited time; (3) The cost investment is high. The price of a small refuge cabin is as high as 2 million. The daily operation and maintenance cost of the cabin is high, and it is expensive to rescue the refugees in the cabin to the ground. At the same time, these existing equipment can only be used by underground workers in emergencies. They passively wait for rescue from ground personnel and cannot actively enable trapped people to escape quickly. According to the investigation and analysis of coal mine accidents, when sudden accidents such as gas explosions and coal dust explosions occur underground, among the final casualties, about 20% died of trauma and burns, and 80% died of carbon monoxide poisoning and suffocation due to lack of oxygen. Most of these 80% of deaths had the possibility of escape in the early stage of the accident. It can be seen that traditional underground protection equipment can no longer meet the requirements of modern underground workers to escape. In terms of protecting the safety of underground workers, it is still necessary to develop safety devices that are more suitable for underground workers to escape when accidents occur.

[0003] In view of this, in order to improve the feasibility and economy of using underground safety equipment, and at the same time make up for the lack of escape protection devices for underground space operations and ensure safe production, the present invention is specially proposed. Summary of the invention

[0004] The purpose of the present invention is to provide a quick escape device and method for underground space operation in coal mines to solve the above-mentioned technical problems existing in the prior art.

[0005] The objective of the present invention is achieved through the following technical solutions:

[0006] The rapid escape equipment for underground space operations in coal mines of the present invention comprises a main pipeline 1 for the escape equipment, on which two escape rings 2 are arranged, namely an upper escape ring and a lower escape ring, a support column 5 is arranged between the two escape rings 2, an oil pipeline 6 is arranged inside the support column 5, one end of the oil pipeline 6 is connected to the fuel storage chamber in the upper escape ring, and the other end is connected to a micro jet engine 9, which is arranged at the bottom end of the lower escape ring, a rolling pulley 8 is arranged between the escape ring 2 and the main pipeline 1 for the escape equipment, a retractable system is arranged inside the escape ring 2, and a lighting system is arranged on the escape ring 2.

[0007] The method for realizing the rapid escape of underground space operation by the above-mentioned rapid escape equipment for underground space operation in coal mines comprises the following steps:

[0008] If a sudden or spreading accident occurs to workers during underground operations:

[0009] First, the operator should wear the respirator correctly to protect the respiratory system of the operator, prevent the dust or other toxic and harmful gases in the underground space from being inhaled into the body, and wear a safety helmet to protect the head from injury;

[0010] Then quickly run to the escape equipment main pipe and turn on the retractable system controller set on the side wall of the escape equipment main pipe;

[0011] Then the retractable transverse pedal and the end baffle are quickly ejected to form a simple escape room consisting of the end baffle, the retractable transverse pedal, the retractable side baffle and the side of the escape equipment main pipe;

[0012] Next, the operator enters the escape room and fastens the safety belt set in the retractable side baffle around the waist;

[0013] Finally, by operating the power system controller arranged on the top of the lower escape ring, the escape room is driven to slide forward or upward until it reaches the ground.

[0014] Compared with the prior art, the rapid escape equipment and method for underground space operation in coal mines provided by the present invention, when using the present invention for underground space operation, the escape device is usually retracted, and the retractable system will be activated for escape only in case of emergency, which will not affect the normal progress of underground operation, and is not limited by the actual working environment. Compared with the traditional escape ladder, the equipment can realize the rapid escape of underground workers, and the cost of the escape equipment is low. Multiple escape equipment can be set up on the underground working surface, which greatly improves the safety and feasibility of underground escape equipment. At the same time, the invention can be recycled and has low operation difficulty. According to the needs of practical applications, the weak feasibility of underground space operation safety equipment is improved, and the lack of escape protection device for underground space operation is compensated. It plays a practical protective role for workers working in underground space of coal mines. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The contents not described in detail in the examples of the present invention belong to the prior art known to professionals in the field. If no specific conditions are specified in the examples of the present invention, the conditions are carried out according to the conventional conditions in the field or the conditions recommended by the manufacturer. If the manufacturer is not specified in the reagents or instruments used in the examples of the present invention, they are all conventional products that can be purchased commercially.

[0029] The rapid escape equipment for underground space operations in coal mines of the present invention comprises a main pipeline 1 for the escape equipment, on which two escape rings 2 are arranged, namely an upper escape ring and a lower escape ring, a support column 5 is arranged between the two escape rings 2, an oil pipeline 6 is arranged inside the support column 5, one end of the oil pipeline 6 is connected to the fuel storage chamber in the upper escape ring, and the other end is connected to a micro jet engine 9, which is arranged at the bottom end of the lower escape ring, a rolling pulley 8 is arranged between the escape ring 2 and the main pipeline 1 for the escape equipment, a retractable system is arranged inside the escape ring 2, and a lighting system is arranged on the escape ring 2.

[0030] The lighting system includes an LED lamp 7, a lighting switch 11, and a battery 12. The battery 12 is placed at the bottom end of the escape equipment main pipe 1 through a floor cover, and the battery 12 is electrically connected to the lighting switch 11 through a power pipeline. The lighting switch 11 is installed on the side wall of the bottom end of the escape equipment main pipe 1. The LED lamp 7 is respectively installed at the top of the upper life ring and the bottom end of the lower life ring. The lighting switch 11 is connected to the LED lamp 7 through a power pipeline.

[0031] The retractable system includes a retractable transverse pedal 18, a retractable side baffle 3 and a gas generator 13, and a protective shell is provided on the outer layer. The protective shell is fixed to the side of the escape equipment pipeline by bolts. The gas generator 13 is connected to the retractable system controller 10. The retractable transverse pedal 18 and the retractable side baffle 3 are connected to the end baffle 4 by a buckle 17. The retractable system controller 10 is installed on the bottom side wall of the escape equipment main pipeline 1.

[0032] The gas generator 13 includes a gas generator and its filling chamber, and a porous compressed air bag. The gas generator filling chamber is connected to the porous compressed air bag through a pipeline, and a perforated partition is arranged in the middle. When the porous compressed air bag pops out, it drives the entire retractable system to pop out, forming a simple escape room composed of an end baffle 4, a retractable lateral pedal 18, a retractable side baffle 3, and the side of the escape equipment main pipe 1. The retractable side baffle 3 is provided with a safety belt 16.

[0033] During the operation of the micro jet engine 9, the air is first compressed by the compressor of the micro jet engine 9, and then enters the combustion chamber to mix with the fuel and ignite to produce combustion gas. The combustion gas then enters the turbine behind the combustion chamber to drive the turbine to rotate. Finally, the combustion gas is ejected through the exhaust port of the micro jet engine 9, generating an upward thrust, which pushes the escape equipment to slide quickly forward or upward to the ground.

[0034] The method for realizing the rapid escape of underground space operation by the above-mentioned rapid escape equipment for underground space operation in coal mines comprises the following steps:

[0035] If a sudden or spreading accident occurs to workers during underground operations:

[0036] First, the operator should wear the respirator correctly to protect the respiratory system of the operator, prevent the dust or other toxic and harmful gases in the underground space from being inhaled into the body, and wear a safety helmet to protect the head from injury;

[0037] Then quickly run to the escape equipment main pipe and turn on the retractable system controller set on the side wall of the escape equipment main pipe;

[0038] Then the retractable transverse pedal and the end baffle are quickly ejected to form a simple escape room consisting of the end baffle, the retractable transverse pedal, the retractable side baffle and the side of the escape equipment main pipe;

[0039] Next, the operator enters the escape room and fastens the safety belt set in the retractable side baffle around the waist;

[0040] Finally, by operating the power system controller arranged on the top of the lower escape ring, the escape room is driven to slide forward or upward until it reaches the ground.

[0041] The sudden accidents include dust explosion, gas explosion, and roof collapse; the spreading accidents include fire and flood.

[0042] From the above, it can be seen that the rapid escape equipment and method for underground space operations in coal mines according to the embodiments of the present invention are simple and easy to use. They are usually in a retracted state and will not affect the normal operation of underground operations. At the same time, the number of escape equipment can be adjusted according to changes in the working environment. The retractable equipment is combined with the power equipment. When an emergency occurs in underground operations, the power equipment controller can be operated to drive the escape room to slide upward quickly and escape from the scene as soon as possible. Compared with traditional escape ladders, the escape equipment can achieve rapid escape from underground operations and increase the probability of survival of operators. At the same time, the equipment can be recycled, which greatly improves the economy and feasibility of underground operation escape equipment, improves the weak feasibility of underground space operation safety equipment, and makes up for the lack of escape protection devices for underground space operations.

[0048] The above-mentioned coal mine (underground space operation rapid escape equipment realizes the method of rapid escape from underground operation, comprising the steps of:

[0049] If workers encounter sudden accidents (dust explosion, gas explosion, roof collapse, etc.) or spreading accidents (fire, flood, etc.) while performing underground operations,

[0050] First, the operator should wear the respirator correctly to protect the respiratory system of the operator, prevent the dust or other toxic and harmful gases in the underground space from being inhaled into the body, and wear a safety helmet to protect the head from injury;

[0051] Then quickly run to the escape equipment main pipe and turn on the retractable system controller set on the side wall of the escape equipment main pipe;

[0052] Then the retractable transverse pedal and the end baffle are quickly ejected to form a simple escape room consisting of the end baffle, the retractable transverse pedal, the retractable side baffle and the side of the escape equipment main pipe;

[0053] Next, the operator enters the escape room and ties the safety rope set in the retractable side baffle around his waist;

[0054] Finally, by operating the power system controller set on the top of the lower escape ring, the escape room is driven to slide upward until it reaches the ground.

[0055] Specific implementation process:

[0056] If no emergency occurs during underground operations, the escape equipment is in a state of waiting for rescue, and the retractable system and the end baffle are retracted to the side of the main pipeline of the escape equipment. At this time, the main pipeline of the escape equipment can supply water to the underground operations, greatly improving the convenience of underground operations.

The retractable system responds quickly, and the retractable horizontal pedal pops out together with the end baffle to form a simple escape room. The operators enter the simple escape room and put on the safety belts set in the escape room correctly, operate the power equipment controller to make the escape room slide upwards, and lead the operators to escape from the scene as soon as possible.

[0058] The working principle of the present invention is:

[0059] When workers are performing underground operations, they connect the escape equipment to the water pipe in case of emergency. The escape equipment is in a retracted state on a daily basis and will not affect the normal progress of underground operations. The escape ring is connected to the escape main pipe through a rolling pulley, which can reduce the resistance of the escape room when it slides upward. The retractable escape equipment is combined with the power equipment. When an emergency occurs in the underground operation, the operator can operate the power equipment controller to make the escape room slide upward for quick escape and escape from the scene as soon as possible, thereby increasing the probability of survival of the operator. At the same time, the escape equipment is reusable, which greatly improves the economy and feasibility of the escape equipment for underground operations.
