A kind of automatic slag gas separation device and method for coal mine

Abstract

The invention provides an automatic slag gas separation device and method for coal mines, belonging to the technical field of slag gas separation devices. It is located between the pipeline and the inner side wall of the separation tank, the upper end of the pipeline is connected to the feed port, and the side wall of the lower end of the pipeline is provided with a number of guiding and diverting holes. The automatic slag gas separation device and method for coal mines removes the gas slag mixture generated during the drilling construction process through the combined action of a separation tank, a pipeline, a spiral path extension plate, a guide shunt hole, a filter sheet, a wave plate and an anti-clogging mechanism. Effective separation and corresponding avoidance of dust generation improve the safety of underground production in coal mines and reduce the impact of the underground working environment on the health of workers.

Description

technical field [0001] The invention relates to the technical field of slag gas separation devices, in particular to an automatic slag gas separation device and method for coal mines. Background technique [0002] In recent years, with the increase of mining depth of coal mines, it has become more and more common to encounter various complex geological coal seams, which increases the difficulty of underground drilling construction in coal mines, especially the treatment of slag in the drilling process. There are two main ways to deal with the slag during the construction of the hole. One is to wash the slag with water as the medium to discharge it out of the hole, and the other is to use the wind as the medium to use the wind flow to carry the slag out of the hole. . [0003] For the treatment of slag in the process of drilling construction of soft and broken complex coal seams, the wind-driven treatment method is usually used. The reason is that the water-mediated slag tre...

Problems solved by technology

[0003] For the treatment of slag chips in the drilling construction process of soft and broken complex coal seams, wind power is usually used as the medium for treatment. The problem of collapse caused by the weak borehole wall makes the hole wall collapse to form waste holes. Therefore, in order to reduce the generation of waste holes, when drilling into soft and broken complex coal seams, the downhole air source or nitrogen gas source will be used to transport to the drill bit for cutting position, using the air flow to carry the slag to the outside of the hole. Although this slag treatment method can reduce the collapse probability of the soft and broken complex coal seam borehole wall, a large amount of dust will be generated during the slag discharge process, which will lead to underground dust in coal mines. Exceeding the standard will seriously affect the safety of production and personnel health in coal mines

[0004] At present, in order to solve the above-mentioned problem of excessive dust, the dust removal method of spraying water or mist is mainly used, but the dust removal effect and dust removal rate of this method are not good, and it cannot fundamentally solve the problem of excessive dust in the drilling site
