Abstract

The invention discloses a safety door at an entrance of a mine. The safety door comprises a door board which is made of an alloy, a hollow structure inside the door board is arranged to be an air exchange chamber, a closer is mounted at the top of the door board, an inductive detector is arranged at the bottom of the door board, an infrared receiving port is arranged at one end of the inductive detector, an infrared transmitting port is arranged at the other end of the inductive detector, an air filter is mounted on the surface of the air exchange chamber, and small ventilation holes are mounted around the air filter. The safety door is applied to mining, has a personnel loss prevention measure, can detect prohibited articles when entering from the door, can exchange air, is high in practicability and extensibility and novel in design, is a good creative scheme and has a good market popularization prospect.

Description

technical field [0001] The invention relates to the field of mining, in particular to a safety door for a mine entrance. Background technique [0002] Mines include coal mines, metal mines, non-metal mines, building materials mines and chemical mines, etc. Mine scale (also known as production capacity) is usually expressed by annual output or daily output. Annual output refers to the amount of ore produced by a mine every year. According to the size of output, it is divided into three types: large, medium and small. The size of the mine should be compatible with the economically reasonable service life of the mine. Only in this way can we save infrastructure costs and reduce costs. In the mine production process, the mining operation not only consumes the most manpower, material resources, occupies the most funds, but also is the production link with the greatest potential to reduce mining costs. The main way to reduce mining costs is to improve labor productivity and ...
