Abstract
The invention discloses an oxygen increasing method and an oxygen increasing device for a working face of non-coal mine at plateau, which belong to a fixed construction department, a drilling and mining division, safety devices in mines or tunnels or safety devices of the self, and technical fields of transporting, filling, rescuing, venting or dewatering according to IPC (International Patent Classification). The invention relates to non-coal mine at plateau, in particular to mine with the working face being seriously lack of oxygen at plateau. The oxygen increasing method mainly includes the following steps that: impurities such as water, oil, dust and the like containing in outside air are removed through a pretreatment filter device (1); in the treated air, oxygen is separated from nitrogen through a membrane separation device (2); the separated oxygen is pressurized through a pressure device (3); the pressurized oxygen is conveyed to an aerobic middle working face (5) through an oxygen catheter along a main air shaft (4), and oxygen with appropriate concentration is obtained through the regulation of an oxygen control device (6) on the working face, so that the goal of improving the concentration of the oxygen on the working face is achieved. The oxygen increasing method and the oxygen increasing device provided by the invention are suitable for improving the concentration of the oxygen on the working face under the mine at plateau, and the borehole operation environment for miners.
Description
Technical field
Patent of the present invention relates to the plateau non-coal mine, especially the serious ore deposit of plateau down-hole mining work plane anoxic
The mountain.Divide by International Patent Classification (IPC) (IPC) and to belong to fixed buildings portion, creep into mining branch, in mine or the tunnel or the safety device of himself, the technical field of transportation, filling, rescue, ventilation or draining.
Background technology
At present, the non-coal mine operation in the plains region, because height above sea level is low, there is not the problem of working environment anoxic basically in the workman.But in the high altitude localities, because the influence that pernicious gas and ore deposit rock dust dirt etc. pollute in the mining process is added in rarefaction of air, degree of oxygen deficiency is just bigger, seriously influences miner's healthy and labor productivity.
Summary of the invention
In order to solve the work plane anoxic problem of the non-coal mine in plateau, the invention provides a kind of plateau non-coal mine work plane oxygenation method, this method can not only be prevented the generation of altitude sickness, ensures that the miner is healthy and safe, and can improve the work plane operating environment, increase work efficiency.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of plateau non-coal mine getting working face oxygenation method is characterized in that described method is as follows:
