Multi-Duct Borehole Loading Hose for Separate Explosive Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing borehole loading procedures in mining and construction require multiple separate instruments for various tasks, leading to bulkier vehicles, increased difficulty in underground movement, and prolonged operation times, with risks of accidental detonation and interference among hoses and probes.
Innovation Solution
A multi-purpose hose with multiple inner ducts for separate transport of fluids, electrical cables, and sensors, allowing simultaneous performance of borehole loading tasks without mixing components until the borehole, using a flexible insulating separator body to maintain separation and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate instruments and hoses are used for borehole loading tasks, then each task can be performed with dedicated equipment, but the vehicles become bulkier and movement in underground mining environment becomes more difficult
Solution Approach 1:
The patent combines multiple separate instruments and hoses into a single integrated multi-purpose hose device. This hose contains multiple inner ducts that can simultaneously transport different elements (explosive emulsion, water, air, inspection probes, sensors) through separate channels, eliminating the need for multiple separate vehicles and hoses while maintaining all required functions.
Solution Approach 2:
The multi-purpose hose device is designed to perform multiple functions simultaneously: transporting explosive emulsion, injecting water for cleaning, providing air supply, inserting inspection probes, and transmitting sensor data. This universal device replaces several specialized instruments, reducing vehicle bulkiness while ensuring all borehole loading tasks can be performed reliably.
2Reliability
If multiple separate hoses and probes are used for different tasks, then each task has dedicated equipment, but the procedures for positioning, inserting and removing components are repeated multiple times, extending the times required for borehole loading procedure
Solution Approach 1:
The patent merges multiple separate positioning, insertion, and removal operations into a single integrated operation. The multi-purpose hose device allows all components (explosive emulsion, water, air, probes, sensors) to be introduced simultaneously through one hose, eliminating the need to repeatedly position and insert separate instruments for each task.
Solution Approach 2:
The simultaneous transport of multiple elements through the multi-purpose hose enables continuous operation without interruption. All borehole loading tasks (cleaning, inspection, explosive loading) can be performed in one continuous operation rather than through repeated sequential steps, significantly reducing the time required for the procedure.
3Productivity
If explosive emulsion is transported through pressurized circuits, valves, pumps, and hoses, then the explosive is delivered to the borehole, but there is a risk of causing accidental detonation
Solution Approach 1:
The patent segments the transport of explosive emulsion from other pressurized fluids by providing separate inner ducts within the multi-purpose hose. The explosive emulsion travels through its own dedicated duct, isolated from water, air, and other substances, eliminating cross-contamination risks and preventing accidental detonation while maintaining efficient delivery through controlled pressurization.
Solution Approach 2:
The patent uses separate inner ducts as intermediaries to isolate the explosive emulsion from other substances and energy sources. Each duct acts as a protective barrier, ensuring that pressurized water, air, or electrical cables cannot come into contact with the explosive emulsion during transport, thereby eliminating the risk of accidental ignition or detonation.
4Adaptability or versatility
If multiple hoses are used for air supply and explosive transport, then each function is served, but interference problems among multiple hoses occur and spares must be maintained for all hoses
Solution Approach 1:
The patent merges multiple separate hoses (for air supply, explosive transport, water injection) into a single multi-purpose hose device with multiple inner ducts. This integration eliminates interference problems between separate hoses and reduces the number of spare parts needed, as only one hose assembly requires maintenance instead of multiple separate hoses.
Solution Approach 2:
The multi-purpose hose device provides universal functionality by incorporating multiple inner ducts that can simultaneously handle air supply, explosive emulsion transport, water injection, and probe insertion. This single versatile device replaces several specialized hoses, reducing device complexity while maintaining all required functions.
5Adaptability or versatility
If more components are included in the hose system, then more functions can be performed, but more points of failure are introduced
Solution Approach 1:
The patent segments different functional components into separate inner ducts within the hose, each dedicated to a specific function (explosive transport, water injection, air supply, sensor transmission). This segmentation isolates potential failure points, so that a malfunction in one duct does not necessarily affect the others, maintaining system reliability while providing versatile operational capability.

AI summary
A multi-purpose hose is provided, which reduces the time required for the loading procedure of the borehole drillings. The hose has multiple inner ducts, where signal cables, power supply, inspection probes and sensors are introduced, and it further allows injecting different fluids such as air, water, emulsions, etc. separately. The described hose allows transporting the different components to prepare explosive emulsions separately and only combines them by introducing the same inside the borehole drilling in the hose outlet.
