National Institute of Rock Mechanics (NIRM) has completed a geophysical assessment for the proposed Vadhvan Port project, identifying substantial subsurface rock resources required for the development of the major maritime infrastructure project planned along Maharashtra’s western coast.
According to details published in the Ministry of Mines’ Annual Report 2025–26, the study was conducted across three quarry sites in Palghar district to evaluate the availability and engineering suitability of rock material needed for the port’s construction and associated infrastructure works.
The report stated that the Vadhvan Port project is expected to require more than 65 million tonnes of armour rock and aggregates. These materials are essential for large-scale marine construction activities such as breakwaters, reclamation work, and coastal protection structures. Armour rock is specifically used to stabilise offshore and shoreline infrastructure against wave impact and erosion.
As part of the investigation, NIRM carried out geophysical imaging of subsurface rock formations up to a depth of nearly 40 metres. The study identified various geological layers including weathered rock, rock boulders, destressed formations, and hard rock deposits considered suitable for construction purposes.
Officials stated that the assessment was aimed at improving planning for quarry operations, material extraction, and deployment during the construction phase of the port project. The findings are also expected to help authorities identify suitable extraction zones while reducing uncertainties related to material availability.
The Vadhvan Port project is among India’s major planned deep-draft port developments and is expected to significantly strengthen maritime infrastructure and cargo-handling capacity on the country’s western coastline.
The Ministry of Mines included the study under the activities undertaken by NIRM, an autonomous institution specialising in rock engineering, mining, and geotechnical investigations for infrastructure and industrial projects.
The report did not specify the overall project cost, construction schedule, or details regarding agencies responsible for quarry operations. However, the findings confirmed the presence of significant rock reserves within Palghar district capable of supporting the engineering requirements of the proposed port development.
Headquartered in Bengaluru, NIRM operates under the Ministry of Mines and conducts specialised research related to rock mechanics, mining, and geotechnical engineering projects across India.
