Problems solved by technology

[0002] In the process of mine mining, for the newly opened mine area, because the coal seam contains more gas, the gas content inside the newly opened mine area is relatively high, if the high concentration of gas gas is not discharged quickly, it is easy to cause a gas explosion accident , the existing method is to use the original mine exhaust system to connect a section of new pipeline to the original mine exhaust system to discharge the gas inside the newly opened mine, but this method simply uses the original mine exhaust The ventilation system draws air, and the suction gas has only one point of the air inlet, and the exhaust air pressure of the newly opened mine will also be subjected to the partial pressure of other exhaust points. distant area

Abstract

The invention relates to an extended flow guide type mine gas accelerated discharge system. The extended flow guide type mine gas accelerated discharge system comprises a new mining area moving device, a switchable accelerated ventilation device and an extended protection air inlet device, wherein the switchable accelerated ventilation device is installed on the new mining area moving device. According to the extended flow guide type mine gas accelerated discharge system, the switchable accelerated ventilation device is combined with the extended protection air inlet device, air flow can be input into a new mining area by utilizing a side wall ventilation device or a main ventilation device of the new mining area through the switchable accelerated ventilation device, and air flow in the new mining area is accelerated, so that high-concentration air in the new mining area is accelerated to be exhausted through an original mine exhaust system.

Description

technical field [0001] The invention relates to an accelerated discharge system, more precisely an extended diversion type mine gas accelerated discharge system. Background technique [0002] In the process of mine mining, for the newly opened mine area, because the coal seam contains more gas, the gas content inside the newly opened mine area is relatively high, if the high concentration of gas gas is not discharged quickly, it is easy to cause a gas explosion accident , the existing method is to use the original mine exhaust system to connect a section of new pipeline to the original mine exhaust system to discharge the gas inside the newly opened mine, but this method simply uses the original mine exhaust The ventilation system draws air, and the suction gas has only one point of the air inlet, and the exhaust air pressure of the newly opened mine will also be subjected to the partial pressure of other exhaust points. more distant areas.
