The invention relates to the technical field of coal mining, and discloses a stripe type coal underground gasification system and production method. The end of the directional gas injection channel isdrilled and penetrated to form an injection and exhaust passage through the construction of narrow strip gasifier; by entering a ignition pipe to the breakthrough point of the injection and exhaust channel in the gas injection line of the gasifier, the ignition pipe is input to high calorific value combustible gas and oxygen, and coal seam ignition in the gasifier is carried out; the gas injection control is carried out through an equal distance arrangement of the hot melt elastic connector on the air injection line in the gas injection channel, so that gas injection points can rollback at intervals with a directional movement of a flame working face; and variation of temperature value can be monitored by setting temperature monitoring drill. The mine coal seam floor rock tunnel is used for carrying out the const
