MINE HILL - Crews worked to fill a growing sinkhole that recently opened up on the front yard of a Morris County family's home.

As News 12 previously reported, the sinkhole opened up earlier this month and has since gotten even bigger.

Homeowner Andrew Kauff says that the 150-year-old mine shaft hole continued to grow, as sides collapsed into the pit nearly 30 feet deep.

Crews are placing boulders and concrete inside the hole. They expect to have it filled by Monday so that they can fill the hole with dirt and rocks as a permanent solution.

Some good Samaritans have donated material and equipment to help keep down the cost, which is expected to be thousands of dollars.

The mayor of Mine Hill Township says maps are available that can help determine which other areas are at risk to similar sinkholes.
