Problems solved by technology

[0007] Aiming at the existing problems of manually judging the quality of borehole exploration, the present invention provides a method for detecting the quality of geological exploration boreholes, which automatically compares and detects the exploration strata of the inspection hole and the original borehole, and conducts an automatic comparison and detection of the strata of the inspection hole and the original borehole. Rapid and batch comparison to improve the speed of stratum verification; build the stratum difference discrimination standard into the model to improve the accuracy of stratum verification

Embodiment 1

[0057] The invention provides a set of drilling quality detection method based on quick comparison between the inspection hole and the original geological exploration drilling stratum. The evaluation model is built in the geological exploration intelligent management platform (PC terminal web page, mobile phone APP), and the user can check it according to the technical requirements in advance. Compile / customize the drilling quality inspection standard, then select the drilling (original drilling) and inspection hole to be inspected, and quickly check the original drilling and inspection hole exploration stratum through software operation to judge the exploration quality of the original drilling.

[0058] 1. Customize the exploration stratum comparison project according to the exploration technical requirements.

[0059] combine figure 2 , the stratum check standard can be subdivided into three main standards of stratum naming, stratum stratification and stratum record, and th...

Embodiment 2

[0069] 1. Customize the exploration stratum comparison project according to the exploration technical requirements.

[0070] The stratum check standard is subdivided into three main standards of stratum naming, stratum stratification and stratum record, and the scores can be set for the three main standards. The total score of the stratum check standard is set to 100 points, the stratum naming standard score can be set at 30 points, the stratum layering standard can be set at 30 points, and the stratum recording standard can be set at 40 points. The three main standards can also be subdivided into detailed standards, such as stratum naming can be subdivided into main categories, subcategories, etc., and the standard scores are decomposed accordingly.

[0071] 2. Establish and train an evaluation model based on the comparison items.

[0072] The evaluation model can be operated through software (can be carried out on the PC or APP of the geological exploration management platf...

Abstract

The invention relates to a geological exploration drilling quality detection method. The method comprises: customizing an exploration stratum comparison project according to exploration technical requirements, and further establishing and training an evaluation model; forming an inspection hole in the set range of the geological prospecting drill hole to be inspected, performing image acquisition,recognizing filling lithology distribution, and if the filling lithology distribution of the geological prospecting drill hole is different from that of the geological prospecting drill hole, judgingthat the evaluation result of the geological prospecting drill hole is unqualified; if yes, acquiring data of each comparison item of the inspection hole; and inputting the data of each comparison item of the inspection hole and the geological prospecting drill hole into the evaluation model for evaluation, and giving an evaluation result. According to the method, the drilling quality detection efficiency can be effectively improved, comprehensive, objective and quantitative fine evaluation can be provided for the drilling quality, the adaptability is high, the application condition is wide,the performance is stable, the cost is low, and the method has good application and popularization prospects and objective social and economic benefits.

Description

technical field [0001] The invention relates to the technical field of geological exploration, in particular to a method for detecting the quality of geological exploration boreholes. Background technique [0002] Mobile drilling is the main and most commonly used method in geological exploration of railways, highways, municipal roads, etc. The quality of drilling often directly determines the quality of exploration. Therefore, the quality of drilling must be strictly inspected. [0003] At present, the commonly used drilling quality inspection method is: re-drill the hole near the hole to be inspected (original drilled hole) (for example, the position can be deviated by 0.5-1m, etc.), this hole is called the inspection hole, after the inspection hole is completed, the inspection hole will be inspected. The exploration strata of the borehole are compared with the original borehole (the hole to be inspected) layer by layer, and the quality of the original borehole is judged b...
