Does anyone know the name of this Christmas movie?

It's an older movie that I really like, but I can't remember what it's called. Jaclyn Smith is in it. She has 2 kids. Her husband works for a company that is doing some blasting around the north pole. They are getting a little to close to santa's Christmas village so he goes to her and the kids to show them around christmas village so that they can try to stop the blasting. At first no one listens, but of course in the end, they stop the blasting and save the day. I haven't seen this movie yet this year. I'd like to look it up to see when it's on, but can't remember the name. Can anyone help?
