Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coal rock recognition during drilling relies heavily on human judgment and simple physical detection, leading to misjudgment and limited information acquisition, especially in the context of coal seam fracturing pressure relief, which is crucial for accurate geological monitoring.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If human judgment and simple physical detection means are used for coal rock recognition, then the device complexity is low, but the measurement precision and reliability are poor leading to misjudgment
Solution Approach 1:
The patent combines multiple detection technologies (X-ray fluorescence spectrometry, neutron activation analysis, and gamma-ray spectrometry) into a single integrated detection system mounted on the drill pipe. This merging of multiple analytical methods enables accurate identification of coal and rock types based on their elemental composition, resolving the contradiction between measurement precision and device complexity by achieving high accuracy through integrated rather than separate systems
Solution Approach 2:
The patent replaces manual human judgment with automated spectral analysis instruments. The elemental analyzer system uses physical and chemical properties (elemental composition) to automatically identify coal and rock types, substituting the mechanical system of human visual and tactile inspection with an automated analytical system that provides objective, precise, and reliable recognition without subjective error
2Productivity
If elemental analyzer is integrated on drill pipe for synchronous detection, then the productivity and information acquisition are improved, but the device complexity increases
Solution Approach 1:
The drill pipe is designed with multi-functionality, serving both as a drilling tool and as a carrier for the elemental analyzer detection system. The drill pipe incorporates mounting structures for the X-ray tube, detector, and other analytical components, enabling it to perform both mechanical drilling and real-time geochemical analysis simultaneously. This universal design improves productivity by eliminating the need for separate detection equipment while managing complexity through integrated rather than additive system architecture
Solution Approach 2:
The elemental analyzer system is pre-installed and configured on the drill pipe before drilling operations begin. All detection components, including the X-ray tube, detector, and data processing systems, are prepared and positioned in advance on the drill pipe structure. This preliminary action enables synchronous detection from the start of drilling operations, improving productivity by eliminating setup time and ensuring continuous data acquisition throughout the drilling process
