Mine Reclamation and Dewatering

Mine Reclamation and Dewatering

Mining makes up a large part of our industry here in America. Natural gas, petroleum, and coal, sulfur, and gravel are all examples of minerals and resources we mined in our country. Mines prove useful from a few years to a few decades, but what happens after a mine is closed? Federal laws and state agencies have regulations on the correct way to close, decommission, and remediate a mine. Click To Tweet Mine reclamation is a process that all mines must undertake when they are no longer functioning.

Mine Closure & Reclamation

It might not surprise you, but properly closing up a mine is a time-consuming process and could take years to complete. This is especially true if long-term water treatment or monitoring is necessary. When closing a mine, the following steps need to be taken:

  • Shutting Down: Once all production has ended, contractors will remain to remove equipment and shut down operations.
  • Decommissioning: Parts and equipment are removed and cleaned, pipelines are drained, structures and buildings are demolished, and waste is removed from the site. 
  • Reclamation/Remediation: This long process is designed to return the land to a satisfactory standard and to ensure that close by water sources have acceptable water quality. Reclamation workers need to remove hazardous materials from the site, as well as surrounding trees, grasses, and topsoil.
  • Post-Closure: After closing, continuous monitoring needs to be in place to show whether reclamation processes were successful. This long-term maintenance process might involve treatment of mine discharge water, and occasional monitoring of the effects of the residues left behind.

 

Mine Dewatering

As one would imagine, many mines are below the groundwater level and they can affect groundwater if not properly treated. These mines need to be dewatered in order to prevent operational problems or contaminated water. For a successful mine dewatering operation, it is imperative to set in place groundwater control strategies like pit or mine pumping, and perimeter dewatering to catch lateral groundwater flow to lower levels. Utilizing an Aqua–Barrier® inflatable cofferdam can make your mine dewatering safer, as well as more cost-effective.

Decommissioned Mines and Reclamation Programs

Mine reclamation can be easier with the proper tools like mini-excavators, dredgers, and inflatable cofferdams, especially when you are working below groundwater level. It takes a lot of work and planning to properly decommission a mine, so make sure to learn and follow your state and federal laws pertaining to the process.

3 Safety Considerations for Bridge Repair Projects

3 Safety Considerations for Bridge Repair Projects

Construction work is always risky, but bridge repair projects put workers at an even heightened danger. In fact, according to OSHA, over 14,000 workers are killed on the job per year. And, with more than 56,000 bridges in America deemed structurally insufficient in 2017, more and more workers will be finding opportunity in fixing these outdated structures.

Safe Bridge Repair Projects

Keeping workers safe on bridge repair projects takes the right tools and planning. Check out these three safety considerations for bridge repair projects to see what protective gear and equipment can help keep workers safe on the job.

One of the top risks of working on bridge repair is falling from a high level to a lower one. Make sure to provide workers with equipment specifically designed for bridge work like bridgewalkers, hydra platforms, and UBITs, rather than retrofitting other equipment that isn’t meant for bridge repair.

2) Dewatering and Diversion Equipment

Many bridges take people over rivers, lakes, and other bodies of water and these bridge repair projects typically require dewatering or water diversion. Be sure to use equipment specialized just for this task, like the Aqua-Barrier® Cofferdam. The Aqua-Barrier® cofferdam is a portable, reusable dam that is easy to deploy and store and is ideal for bridge repair projects. Click To Tweet Aqua-Barrier® can be installed 3-5 faster than other older, traditional methods. You can save significant time in the dewatering process and complete your bridge repair projects better and faster than your competition.

3) Eye, Face, and Foot Protection

OSHA requires bridge workers to wear proper safety protection to help prevent injuries. Bridge repair work puts workers at risk for eye and facial injuries because foreign particles from welding, grinding, cutting, or working with concrete can occur, as well as facial damage from extreme winds, dangerous chemicals, smoke, or electrical work. Foot protection is just as important and the correct shoes are important to help prevent slips, falls, and safety from electrical discharge.

Bride Repair & Dewatering Solutions

There are, of course, more safety measures and equipment that can help keep workers safe while doing bridge repair, but these three considerations can help prevent bridge repair related injuries and accidental deaths. Using the best equipment for the project (and used correctly) will help reduce workplace risks and make the job safer. You owe it to your valued employees to do all you can to protect them on the job.
