In the paper, construction and technical parameters of modular hole device for gas-dynamic logging of horizontal degassing open holes drilled from workings are represented. The device includes pneumatic pusher which provides movement of the device into hole with air hose and electric wire, electrically controlled pneumatic distributor, inflatable attachable hole sealer and indicator of gas discharge from isolated location of the hole to its сollar. Recommendations for using the developed device at coal mines are represented.
