The method accurately predicts the outburst disasters of the coal and the gas at the head-on front, applies corresponding preventive measures and is an important premise for ensuring the safe tunneling of the roadway. At present, a drilling cutting index method is taken as a technical means for predicting coal and gas outburst in China, wherein an important index is the drilling cutting quantity, namely the quality of the drilling cutting discharged by drilling when a twist drill rod with the diameter of 42mm drills into a unit length, but the accurate measurement of the drilling cutting quantity has the following problems:
(1) Incomplete chip taking: the underground test environment is complex, particularly the drill cuttings are in the air inlet head to head, and a part of the drilled drill cuttings are blown away and cannot be collected;
(2) The drilling machine footage judgment has subjectivity: the control of the drilling distance is roughly judged by a technician according to the length of a drill rod (such as a 1m long twist drill rod), and the real-time footage cannot be accurately measured;
(3) The cuttings measurements are coarse and not real-time: the drilling machine footage judgment by a technician is subjective, so that the calculation result of the drilling cuttings amount cannot accurately reflect the drilling cuttings amount change of the whole drilling depth in real time;
(4) The drilling state of the drilling machine cannot be judged: the drilling cuttings quantity can not be accurately measured in real time, so that whether the drilling machine is empty or not and whether the drilling state of the drilling machine is normal or not can not be judged;
(5) The digitization degree is low: the measured data needs to be calculated and copied manually by a technician, so that the real-time performance is poor and errors are easy to occur.
