Abstract. The article deals with the issues of occurrence, spread and extinguishing of fires in the mine gas pipelines for the methane removal during degassing of the coal massif and overlying rock layers. The composition of the gas mixture in the gas pipeline, various causes of ignition of gases in the gas pipelines, and specifics of methods for extinguishing fires in mine gas pipelines are considered. Devices which are mounted in various gas pipelines for extinguishing explosions and fires are analyzed. The main drawbacks of these devices are described. Recommendations are made for the ways to improve these devices.
The purpose of the research was to develop such a device for extinguishing fires in mine gas pipelines - a fire stopper of the mine gas pipeline - which is guaranteed to extinguish the flame front moving in the gas pipeline regardless of speed and direction of its movement.
The basis for improving the fire stopper for the mine gas pipeline was the task to create such obstacles which guarantee the extinguishing of the flame front in the gas pipeline by not only dividing it into separate flows and passing through narrow channels, but also by changing the direction of the gas flow by passing it through a labyrinth of narrow channels with a two-stage trap without increasing the gas-dynamic resistance of the device during its operation in the usual mode of pumping gas by vacuum pumps. The device should have small dimensions providing the possibility of its easy installation in the mine or on the surface, and it should be equally effective for extinguishing the flame moving both from the surface and in the mine gas pipelines.
The new technical solution in the design of the fire stopper is proposed. The sketch project of the new design of the fire stopper is shown. A description of its design and operation is provided. The advantages of the new fire stopper design are presented.
This fire stopper designed for the mine gas pipelines has small dimensions and weight, does not require additional equipment for maintenance and can be installed in any part of the gas pipeline, both in the mine workings and on the surface. This fire stopper can extinguish the flame front in both directions and provides little aerodynamic resistance to the movement of the gas flow.

Keywords: coal mine, degassing pipeline, flame front extinguishing, explosions, fire stopper, air inflows, methane concentration.
