Embodiment Construction
[0041] The present invention will be further described below in conjunction with the drawings.
[0042] Such as figure 1 As shown, an intensive mine ventilation resistance measurement method is to establish a ventilation resistance measurement subsystem with each independent roadway as the object, and arrange wind speed sensors reasonably. Air pressure sensors and differential pressure sensors 4 are arranged at the roadway nodes, and the short pipeline 2 The location is also the overlapping location of the long pipeline 1 and the short pipeline 2, which specifically includes the following steps:
[0043] Step 1: Establish a number of ventilation resistance measurement subsystems in the underground roadway with each independent roadway as the object, and select PVC steel wire hose as the pressure measurement pipeline 5 in the resistance measurement subsystem. The pressure measurement pipeline 5 is divided into long pipelines 1 and short pipeline 2;
[0044] Step 2: Make the undergro...
