Dewatering at Stone Mines, Jhumri Telaiya, Jharkhand

Cosmos Pumps tackled wastewater issues in Jhumri Telaiya stone mines, delivering effective solutions for quick recovery and operational success.

Overcoming Subterranean Water Challenges

The Problem:

Wastewater and unwanted water had accumulated in a large stone mine spanning 1.5 km in length and reaching a depth of 45–50 meters. This stagnation persisted for approximately six months, completely halting mining operations.

Impact:

The mine had been shut down for six months, which incurred a total loss of ₹1,800 million, equivalent to ₹10 million per day. The owner tried lots of pump brands but could not find an effective management of the large quantity of wastewater.

Pumps Used:

Submersible Pumps: Full range

Autoprime Pumps: Full range

Objectives:

Cost minimization

Objectives

Long-term sustainability of wastewater

Solution Implemented

The seriousness of the situation called for an effective and immediate solution. Given the substantial volume of wastewater, Mr. Jain, Cosmos Pumps CEO, jokingly suggested developing the site as a boating tourist attraction. Ultimately, based on their experience and reliability, Cosmos Pumps was selected for the work.

  • Planning and Mobilization: The dewatering process was scheduled to be completed within 30 days. Mobilization was completed within 3 days, followed by pump installation within another 3 days.
  • Equipment Deployed: A total of 60 pumps were supplied on a rental basis for the dewatering process. Submersible pumps used were:
  1. 28 pumps of 50 HP
  2. 22 pumps of 35 HP
  3. 10 pumps of 25 HP
  • Implementation: The team commenced dewatering operations immediately after installation. Despite the initial 30-day target, the process was completed in a record 23 days. Dewatering itself was completed within just 17 days, demonstrating exceptional efficiency.

Results

  • Resumption of Mining Activities: Mining activities were soon resumed, and the losses in terms of finance were minimized, and revenue generation was resumed.
  • Financial Recovery: The mine owner saw an excellent financial recovery as activities resumed earlier than expected.
  • Reliability: Cosmos Pumps provided a very practical and reliable solution that exceeded expectations.
  • Customer Satisfaction: The mine owner is highly satisfied with the prompt and effective results obtained.
