Drilling parameter monitoring device and monitoring method of underground drilling machine

Abstract

The invention discloses a drilling parameter monitoring device of an underground drilling machine. The device comprises a shell, an external sensor module arranged at the external of the shell, a dataacquiring module arranged in the shell and connected with the external sensor module through a data wire and used for receiving data sensed by the external sensor module and comprising a single-chipmicrocomputer and a data acquiring card, a control panel arranged on the shell and used for displaying the data received by the data acquiring module and comprising a display screen and a control button, and an underground power supply module comprising a voltage conversion module and a battery interface, wherein the voltage conversion module is arranged in the shell. The invention further provides a drilling parameter monitoring method of the underground drilling machine. The drilling parameter monitoring device and method of the underground drilling machine achieve the beneficial effect of real-time monitoring of drilling parameters of the underground drilling machine.

Description

technical field [0001] The invention relates to the fields of control engineering and geological engineering research. More specifically, the present invention relates to a monitoring device and a monitoring method for drilling parameters of a downhole drilling rig. Background technique [0002] In recent years, with the expansion of the scope and depth of coal mining, the number of high-gas mines has continued to increase, and coal mine safety production accidents have continued to occur. The use of drilling rigs for drilling gas drainage is a fundamental measure to prevent and control gas disasters and accidents and achieve comprehensive gas management. However, at present, in the process of underground gas drainage in coal mines, the monitoring of drilling rig parameters is still completed by manual observation of instruments, manual recording of data and manual judgment of experience, and the recorded data needs to be analyzed manually. The disadvantages of this status ...

However, at present, in the process of underground gas drainage in coal mines, the monitoring of drilling rig parameters is still completed by manual observation of instruments, manual recording of data and manual judgment of experience, and the recorded data needs to be analyzed manually

The disadvantages of this status quo are as follows: First, due to the poor working environment in coal mines and the complex and changeable rock formations, various problems and failures are often encountered during the drilling process. It is difficult to detect the failure of the drilling rig at the initial stage by relying on human experience. Failure to discover and solve problems in time causes the drilling rig to stop drilling before searching for the problem and delaying the progress of the project; second, the drilling rigs in the underground tunnels of coal mines are mostly constructed based on experience. In the case of the same geological conditions and little difference in equipment technology In this situation, there is a certain gap in the drilling technical indicators of different teams. By analyzing the data stored in the monitoring system, the reasons for the differences can be found out and the differences can be narrowed down. Third, the instruments installed on the drilling rig are durable in the harsh environment of the coal mine Poor performance, often damaged due to factors such as low temperature and vibration, cannot reflect the working parameters of the drilling rig well; Vibration) to judge whether the drilling rig is running normally, which is prone to errors. The operator of the drilling rig has to observe and analyze the information of many instruments in a short period of time, which is too difficult
