Deep hole fixed-point sampling device

  Dkq-73s deep hole fixed-point fast sampling device deep hole fixed-point sampling device according to the sampling requirements specified in the standard GB / t23250 underground direct determination method of coal seam gas content, the multi-level injection technology is adopted to realize the sampling while drilling and the fixed-point sampling without removing the drill pipe, and the rapid fixed-point sampling of any point within 60m or more of the coal seam can be realized within 5min
It is a complete set of equipment with high sampling success rate in China
It is applicable to the efficiency inspection of underground drilling in coal mine
Deep hole fixed-point sampling device according to & ldquo; Taper Expansion & rdquo; The hole sealing principle and drainage tee device can controllably collect the gas containing coal ejected during the drilling process of high gas and coal and gas outburst mine construction into the sealed container, so as to avoid personal injury and gas out of limit accidents caused by gas spray hole
The deep hole rapid sampling dust suppression device can also reduce construction dust and improve the level of occupational environmental health, It is one of the accessories of modern production mine drilling construction
