Pakistan Thar Coalfield Dewatering Project

1. Project Overview

• The Thar Coalfield Dewatering Project is a coal mining infrastructure project in Pakistan. Donghong supplied pipeline products for mine water conveyance and dewatering applications, supporting the water management requirements of the mining operation.

• The application required a pipeline solution capable of handling high-pressure water conveyance, demanding mining conditions and long-term continuous operation, with reliable performance throughout the project lifecycle.

2. Donghong Solution

• High-Performance Composite Pipeline for Mine Water Conveyance

• Donghong supplied steel wire mesh reinforced polyethylene composite pipes (SRTP) for the project's mine water supply and dewatering system.

• The reinforced composite structure combines the high strength and pressure resistance of steel reinforcement with the corrosion resistance and lightweight characteristics of polyethylene, providing a durable solution for high-pressure mine water conveyance.

• The solution was selected to provide reliable water transportation under demanding mining conditions while facilitating transportation, handling and installation.
