Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current model tests for underground projects primarily focus on single aspects of rock collapse or water inrush, lacking a comprehensive device to simulate both fractured rock mass collapse and rockfall, as well as fracture water inrush mechanisms simultaneously.
Innovation Solution
A test device comprising a fractured rock mass preparation system with an upper and lower die, a cutterhead, water source loading device, and surrounding rock pressurization system, allowing for the simulation of rock mass collapse, rockfall, and fracture water inrush under varying conditions by forming a molding cavity, cutting the rock mass to create fractures, and controlling water pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate test devices are used for rock collapse research and water inrush research, then each device can be optimized for its specific function, but the device complexity increases and research efficiency decreases
Solution Approach 1:
The patent combines the rock collapse test device and water inrush test device into a single integrated system. The rock mass sample is placed in a pressurization chamber that can simultaneously apply mechanical stress for collapse testing and inject water for inrush testing, eliminating the need for separate devices and reducing overall system complexity.
Solution Approach 2:
The test device is designed with multi-functional capabilities to perform both rock collapse testing and water inrush testing using the same hardware platform. The pressurization chamber, loading system, and measurement instruments serve dual purposes, allowing one device to fulfill multiple research functions that previously required separate specialized equipment.
2Device complexity
If single-aspect model tests are conducted for either collapse or water inrush, then the test setup is simpler, but the research cannot capture the coupled mechanisms of both disasters
Solution Approach 1:
The test device incorporates dynamic control capabilities that allow the researcher to switch between different test modes (collapse-only, inrush-only, or coupled tests) and adjust test parameters in real-time. The loading system can dynamically apply mechanical stresses while the water injection system can simultaneously or sequentially introduce water, enabling flexible research configurations within a single unified platform.
Solution Approach 2:
The device allows for changing test parameters such as stress levels, water pressure, and injection rates to simulate different geological conditions and disaster scenarios. By adjusting these parameters, the same physical device can model various aspects of rock collapse and water inrush mechanisms, as well as their coupled interactions, without requiring physical reconfiguration.
3Adaptability or versatility
If comprehensive dual-aspect testing is performed simultaneously, then both collapse and water inrush mechanisms are researched together, but the device complexity and operational difficulty increase
Solution Approach 1:
The test device incorporates automated control systems and integrated measurement instruments that reduce the need for manual intervention during coupled tests. The system can automatically coordinate the mechanical loading and water injection processes, monitor multiple parameters simultaneously, and record data from both collapse and inrush phenomena, making complex dual-aspect testing more operationally manageable.
Solution Approach 2:
The patent introduces a centralized control system that acts as an intermediary between the operator and the complex test parameters. This control system coordinates the various subsystems (loading mechanism, water injection system, measurement instruments), simplifying the operation of coupled tests by providing unified control and automated parameter management rather than requiring direct manual coordination of multiple independent systems.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables simultaneous simulation of rock mass collapse, rockfall, and fracture water inrush under different stress and pressure conditions, providing comprehensive data for disaster prevention and reduction in underground projects.
Implementation Method 1
the water pressure in the rock mass water storage structure is controlled through the water pump to simulate the fracture water inrush under different water pressures
Implementation Method 2
When the fractured rock mass is pressurized by the surrounding rock pressurization device, the demands of surrounding rock crustal stress in different environments can be simulated, and then the collapse and rockfall of the fractured rock mass can be simulated
