SLBC Tunnel Works Resume After One Year With Safer Construction Method
After a year long pause following a deadly tunnel collapse SLBC works have resumed with a new drilling and blasting strategy focused on worker safety structural stability and timely completion of the crucial irrigation project

- Tunnel works resumed after a year long halt.
- Drilling and blasting method replaced tunnel boring machine.
- Project is key for irrigation and drinking water supply.
Nearly a year after a tragic collapse halted construction the Sri Sailam Left Bank Canal tunnel project has resumed with renewed caution and a revised execution plan. The restart marks a critical step forward for a project that holds major importance for irrigation and drinking water supply in Telangana.
The tunnel work under the SLBC project was stopped last February after a sudden collapse during excavation claimed the lives of eight workers. The accident occurred while work was underway using a tunnel boring machine prompting authorities to suspend mechanical excavation due to safety concerns.
After extensive technical reviews the government has now opted for the drilling and blasting method instead of machine based tunnelling. Officials believe controlled blasting is more suitable given the geological conditions and will help reduce risks during construction. Experts are closely monitoring tunnel roof stability before and after each blast.
Additional safety measures have been put in place including improved ventilation systems and emergency exit arrangements. Engineers are conducting frequent inspections to ensure that past mistakes are not repeated while also maintaining steady progress at the site.
The SLBC tunnel is vital for supplying Krishna river water by gravity to drought prone regions including parts of Nalgonda. With work finally resuming near Srisailam, hopes have been rekindled among farmers who have waited years for assured irrigation.
