Embodiment Construction

[0066] The present invention refers to a water hazard concealed within the concealed seam and surrounding rock, may be induced hazards in the mining process, including goaf water, water-filled column collapse, different bodies of water, fault, collapse column, gas and stress anomaly, ignition point and the like.

[0067] The present invention refers to a concealed configuration Quaternary unconsolidated sediments surface masked or concealed in the surface geological bedrock. Hiding structure including buried faults, folds concealed, concealed ridges, depressions and concealed concealed rock and the like.

[0068] In the present invention, when drilling transient electromagnetic data is calculated, to obtain three-dimensional imaging with clever use Hermit interpolation algorithm, its improvement, based on proprietary algorithms explained stereoscopic imaging data. Wherein, Hermit interpolation algorithm combines the function derivative value, such that the interpolation accuracy i...

Abstract

The invention provides a long-distance advanced detection method for a directional drilling driving working face. The invention belongs to the technical field of geophysical exploration. Drilling transient electromagnetism and drilling radar combined detection can be realized in long-distance (greater than or equal to 500 m) directional drilling at a driving working surface; according to the long-distance advanced exploration working device, the advantages of directional drilling and geophysical exploration are effectively fused, three-dimensional imaging interpretation is conducted on data through a unique algorithm, and roadway rapid tunneling and green, efficient and intelligent mining of a coal mine are guaranteed.

Description

Technical field [0001] The present invention belongs to the field of geophysical exploration technology, and involves a working device and data processing interpretation method for providing long-distance geological disasters in the roadway to provide long-distance geological disaster prior detection. Background technique [0002] With the gradual impact of my country's coal development, complex geological structure and hidden water damage, the impact of coal mine safety production is increased, especially in the process of coal mine roadway, facing complex unknown geological conditions, advanceability and the advancement of geological security technology Accuracy puts higher requirements. Coal mines underground roadway must guarantee safety, and the implementation of rapid tracting is more necessary to provide safety-based, and involve rapid depth, advanced detection, and comprehensive control. The advanced probing of lanes safe and quick tracing is both accurately acquiring eff...
