Abstract

The invention discloses a drilling machine drilling state monitoring device and monitoring method. The drilling machine drilling state monitoring device comprises a drilling posture monitoring unit arranged between a drill bit and a drill rod and a drilling fluid pressure monitoring unit arranged between a water braid and a drilling fluid conveying rubber pipe. The drilling attitude monitoring unit is used for measuring, storing and transmitting drilling attitude parameters, and the drilling fluid pressure monitoring unit is used for measuring, storing and transmitting drilling fluid pressure parameters. According to the method, drilling fluid and drilling attitude measurement is completed in the drilling state process of the drilling machine, effective drilling fluid data values are extracted from drilling fluid pressure data monitored in real time, effective drilling attitude data values are extracted from drilling attitude data monitored in real time, and the drilling state of the drilling machine can be accurately monitored by combining the two data values; the method is simple and convenient, and the whole drilling process can be known in real time under the condition that extra workload and application cost are not increased.

Description

technical field [0001] The invention belongs to the technical field of borehole measurement, and relates to a drilling rig drilling state monitoring device and a monitoring method. Background technique [0002] Borehole gas drainage is the most commonly used method of gas control in coal mining, and mines require a large number of boreholes. The response of the underground drilling rig in coal mines is closely related to the state of the rock mass. During the drilling process, the construction status of the drilling rig can be inferred based on the response of the drilling rig during drilling. However, at present, the acquisition of such information mainly depends on the experience of the construction personnel. It will inevitably lead to unreliable information acquisition. The online monitoring and data acquisition software can realize the networked ground monitoring and data acquisition, calculation and management of drilling rig equipment working conditions parameters, o...
