Abstract
A cooling capacity arrangement system for a coal face in a high temperature mine relates to a system capable of performing effectively cooling down to the coal face of a coal pit and creating a low-temperature environment. The system comprises four parts: a use site, a cold water flow and return pipe and configuration component, an air cooler set and a sprinkling component. The use site comprises an intake channel, a wind inlet gate roadway, the upper opening and the end opening of the mining face, and a coal face, and the upper opening of the mining face is directly communicated with a main air return channel; the cold water flow and return pipe and configuration component comprises a cold supply pipeline, a water return pipe and the like, and the cold supply pipeline transmits low-temperature cold water to the air cooler set, and the cold water is returned through the water return pipe after heat exchange; and a spray pipe also can be connected to the provide and return pipe, and the low-temperature cold water or the water after heat exchange by the air cooler can be directly used to realize secondary cooling down according to real demands. The utility model has the advantages that the cold air distance is short, and the distance to the end opening of the mining face is less than 200m; and a mini-type air cooler set can be adopted, so that the installation and move are convenient; and a spraying system is further provided, so as to solve the problems that the coal face is hot at the upper part and cold at the lower part, and the cold supply is uneven.
Description
Technical field
The utility model relates to a kind ofly effectively lowers the temperature to the mine coal-cutting work plane, creates the system of low temperature environment.
Background technology
In the coal reserves that China is verified, the coal reserves of 1000～2000m depths accounts for 53.2% of gross reserves, so the degree of depth of pit mining is in continuous increase, along with the continuous increase of the pit mining degree of depth, mine job site working environment is more and more warmmer, and the instant heating evil is more and more serious.There are many getting working face airflow temperatures to mine in China above 30 ℃ according to statistics.So many heat evil mine, if do not work out ripe falling temperature technique and equipment, the exploitation of coal resources and utilize will be very difficult influence the sustainable development of whole national economy, so the mine elevated temperature heat does harm to and become one and can not be ignored and urgent problem.
Sum up domestic and international high-temperature mine coal-face cold configuration-system, mainly contain following several:
First kind is arranged in inlet air crossheading entrance to air cooler (evaporimeter): its main feature is: the equipment installation and transportation are convenient, do not influence pedestrian and operation; Major defect is: need lay the major diameter air duct, the cold wind of handling through air cooler is transported near the work plane end opening; Or need not air duct, directly the air themperature with whole inlet air crossheading drops to certain limit, but the working face cooling effect is relatively poor.
Directly at work plane small-sized air cooler is installed for second kind: its main feature is that the cold that air cooler distributes all is effective cold; Major defect is: need follow the face of adopting and move and move, chilled water all need move for return pipe, and the mobile working amount is big, and air cooler easily collects ash, needs regularly to clean, and maintenance workload is big, and does not solve the elevated temperature heat evil of inlet air crossheading.
The third sets up the cold wall of special-purpose cooling: the cold wall of logical cold water in the inlet air crossheading is established a special-purpose cold wind tunnel, established in the cold wind tunnel.Its major advantage is that area of dissipation can be built on demand; Major defect is: windage is big, can only be used for the short job site cooling of air supplying distance; Another major defect is: cold wall easily collects ash, influences cooling-down effect; The 3rd shortcoming be, because fortune coal belt or mine car is current, the inlet air crossheading is difficult for airtight, and hot blast is sneaked into and caused cooling-down effect not good, and the cold wind fed distance is long, the working face cooling weak effect.Set up independent cooling tunnel, investment is big.
Existing Chinese patent application has " a kind of temp lowering device for deep mine " (application number 200710025002), comprise ground unit and underground unit, the ground unit comprises compressor, condenser, expansion valve and evaporative condenser, underground unit comprises down-hole heat exchanger and ventilator, the bottom heat-exchange working medium outlet of evaporative condenser is connected with the import of down-hole heat exchanger, and the outlet of down-hole heat exchanger is connected with the heat exchange of top part working medium import of evaporative condenser.
