MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202511122573 A) filed by Chandigarh University, Mohali, Punjab, on Dec. 5, 2025, for 'geo-adaptive rock bolt system.'
Inventor(s) include Kuldeep Kumar; Namrta Tanwar; Vishal Sharma; and Dr. Rashmi Sharma.
The application for the patent was published on Jan. 23, under issue no. 04/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a Smart Geo-Adaptive Rock Bolt System for use in mining, tunnelling and geotechnical reinforcement applications. The system incorporates a self-adjusting preload mechanism employing a shape memory alloy actuator or hydraulic actuation unit configured to autonomously vary bolt tension in response to dynamic ground movement. A multi-sensor array embedded within the bolt monitors strain, vibration, corrosion and temperature parameters in real time. The system is powered through piezoelectric energy harvesting, thereby eliminating dependence on external power sources or periodic battery replacement. An onboard processing unit executes AI-based analysis of sensor data to identify patterns indicative of bolt degradation or potential rock failure and triggers mechanical adjustment or wireless alerts via BLE or LoRa communication modules. The modular design of the bolt enables integration with both new installations and existing support systems, providing continuous structural health assessment and adaptive load regulation in underground or unstable environments."
