Abstract

The invention discloses a coal roadway driving working face coal seam gas content non-contact dynamic continuous measurement system and method. The measurement system comprises a multi-parameter dynamic acquisition system, a monitoring system and a gas content resolving system. The multi-parameter dynamic acquisition system is used for acquiring the coal roadway return air gas concentration, the roadway section area, the roadway section perimeter, the distance from a sensor to a tunneling head and the working face wind speed of a parameter acquisition point, and transmitting information to thegas content resolving system through the monitoring system; and the gas content resolving system is used for acquiring, processing and displaying multi-parameter data signals and controlling a driving module of the multi-parameter dynamic acquisition system. According to the method corresponding to the system, point-line-surface-body comprehensive analysis inversion can be carried out on multi-parameter information obtained by the system. The system and method can be widely applied to observation and research of the coal seam gas occurrence law of the coal roadway driving working face.

Description

technical field [0001] The invention belongs to the field of mine gas prevention and control, and in particular relates to a non-contact dynamic continuous measurement system and method for coal seam gas content in a coal roadway driving face. Background technique [0002] Mastering the distribution and occurrence laws of coal seam gas is the key to implementing precise gas control. At present, the measurement methods for coal seam gas content mainly include: direct method to measure gas content and indirect method to measure gas content. The direct method is to take coal samples through drilling, and finally determine the gas content through downhole desorption and surface desorption, and the indirect method to measure gas content. The content is deduced from the gas content by measuring the gas pressure. The traditional gas content measurement is a contact point prediction method, which is mainly carried out by drilling on the coal wall, fixed-point sampling or pressure m...
