Coal mine explosion kills 9 leaves trapped underground

I'm so sorry to hear that. A coal mine explosion can be a devastating and tragic event, and my heart goes out to the families of the victims.

According to your message, 9 people have lost their lives in the explosion, and there are others who are still trapped underground. I can only imagine the fear and uncertainty that the families of the trapped miners must be feeling.

Can you tell me more about the explosion? What happened, and are there any updates on the rescue efforts?
