MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202621029007 A) filed by Dr. Abhishek Sharma; Prof Sanjay Khadagade; Ansh Majhi; Ayush Choubey; Maharshi Chouhan; Anurag Anand; and Ayush Anand, Bhopal, Madhya Pradesh, on March 11, for 'design and implementation of solar- powered dewatering in mining operations.'
Inventor(s) include Dr. Abhishek Sharma; Prof Sanjay Khadagade; Ansh Majhi; Ayush Choubey; Maharshi Chouhan; Anurag Anand; and Ayush Anand.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "Design and Implementation of Solar- Powered Dewatering in Mining Operations Water accumulation in mining pits is a critical challenge that can disrupt operations, damage equipment, and create hazardous working conditions. Conventional dewatering methods typically rely on diesel-powered or grid-connected pumping systems, which often result in high operational costs, environmental pollution, and dependency on reliable electricity infrastructure. These limitations highlight the need for an efficient and sustainable water management solution, particularly for mining sites located in remote or off-grid areas. The present invention proposes a solar-powered automated dewatering system integrated with IoT-based monitoring and embedded control technology. The system utilizes solar photovoltaic panels to generate electrical energy, which is regulated through a charge controller and stored in a battery for continuous operation. An ESP32 microcontroller acts as the central control unit, receiving input from water level sensors installed in the mining pit. Based on predefined thresholds, the system automatically activates a submersible pump through a relay module to remove accumulated water, ensuring safe and stable working conditions. Additionally, the invention incorporates a cloud-based monitoring platform using Firebase to enable real-time remote monitoring of key system parameters such as water level, pump status, battery voltage, and solar energy generation. A local LCD interface also provides on-site system status information. The proposed system reduces dependency on fossil fuels, lowers operational costs, improves safety through automation, and promotes environmentally sustainable mining practices. The modular architecture further allows the system to be adapted for other applications including agricultural irrigation, industrial drainage, and flood management."
