Title:
COAL AND GAS BURST RISK PARAMETER DRILLING AND PREDICTING INTEGRATED METHOD
Document Type and Number:
WIPO Patent Application WO/2014/023111
Kind Code:
A1
Abstract:
A coal and gas burst risk parameter drilling and predicting integrated method. In a process of constructing and drilling (7) a coal bed by a drilling machine (1), a guide pipe (12) is arranged in an opening of a drilled hole (7), a slag collector (11) and a gas exhaust pipe (3) are connected through the guide pipe (12), a gas concentration sensor (4) and a flow speed sensor (5) are arranged in the gas exhaust pipe (3), a weight sensor (10) is arranged at the bottom of the slag collector (11), a counter (2) and a torque sensor (6) are arranged on the drilling machine (1); during drilling (7), coal dust enters the slag collector (11) through the guide pipe (12), the coal dust weight information is transmitted to a multi-information processor (8) by the weight sensor (10); the gas information is transmitted to the multi-information processor (8) by the gas concentration sensor (4) and the flow speed sensor (5); the torque of the drilling machine (1) and the quantity of drill stems (13) are transmitted to the multi-information processor (8) by the torque sensor (6) and the counter (2) on the drilling machine (1); and the burst risk of coal and gas in a region is predicted. The coal and gas burst risk parameter drilling and predicting integrated method provides multi-information quantity for the prediction of the burst risk of the coal and the gas, so that the accuracy for predicting the burst risk of the coal and the gas is improved.
