Drilling operation efficiency evaluation system and method based on data feature recognition

Abstract

The invention relates to a mining drilling operation efficiency evaluation system and method based on data feature recognition. The system is composed of an explosion-proof rechargeable battery cylinder, an explosion-proof measurement probe tube and an explosion-proof controller. In the drilling process of the system, the explosion-proof measurement probe tube is used for continuously measuring and storing drilling operation state data, and finally the drilling operation efficiency is comprehensively evaluated according to measurement parameters. The system is low in price, a wireless transmission mode is adopted for data exchange between devices, connecting cables are saved, a current conventional coal mine underground drilling process is not changed, the drilling operation state data are stored in real time in the drilling process, the drilling depth and the coal seam lithology are automatically recognized, the labor cost for manual hole depth measurement and coal seam lithology recording is saved, the drilling depth counterfeiting risk is prevented, and the coal mine drilling work efficiency is improved. The system is easy and convenient to install and operate, the hole opening orientation process is simplified, and the system is suitable for drilling tools of different specifications and sizes used for coal mine underground drilling and has universality and explosion-proof performance.

Description

technical field [0001] The invention relates to a drilling operation efficiency evaluation system and method, belonging to the field of drilling technology, in particular to a mining drilling operation efficiency evaluation system and method based on data feature recognition. Background technique [0002] Drilling efficiency evaluation is a technical abbreviation for the evaluation of the deviation between the actual drilling trajectory and the design trajectory formed by the drilling hole, the length of drilling labor and the evaluation of drilling quality. [0003] Underground coal mine drilling operations are generally divided into the above steps: complete the drilling operation according to the design requirements, trip out and evaluate the quality of the drilling trajectory. [0004] During the drilling operation, in order to determine the properties of the rock formation in front of the drill bit, it is common to manually collect the rock samples returned from the hol...

Problems solved by technology

[0004] During the drilling operation, in order to determine the properties of the rock formation in front of the drill bit, it is common to manually collect the rock samples returned from the hole during the drilling process to analyze and determine the properties of the rock formation. The rock samples collected by this method are easily affected by different lithology. pollution, which brings difficulties to rock formation analysis and even leads to erroneous analysis results, and at the same time increases certain labor costs

[0005] The cost of drilling workers in underground coal mines is generally calculated according to the drilling footage, and in order to evaluate the difference between the actual drilling trajectory and the design of the drilling trajectory, it is also necessary to record the drilling depth value. The current method manually records the number of drill pipes at the hole mouth. Putting the cable length into the borehole, borehole imaging method, borehole radar, using a special push rod, etc., the above methods use artificial statistics, there are human errors introduced by cheating, a waste of human resources and labor disputes between the two sides, there is a relatively large Big limitations; although some companies have proposed a technical method based on image AI to identify hole depth in the market, this method is only suitable for working environments with low dust and high visibility

[0006] At present, the underground drilling trajectory storage measurement system in coal mines has begun to be widely used. At the same time, the hole directional measurement system and the drilling depth measurement system have also begun to be applied in some coal mines. The operating efficiency evaluation system is still in the stage of research and program demonstration. This product has not been promoted and used in the market, and there is also a lack of clear reports.
