Researching an old family photo...

Hello! I am researching an old family photo that my family has but no one is sure what/who this photo is of. Some of the basic information we do know about our ancestry is:
1. My Great-Grandmother was born Prešov, Slovakia around 1893 and arrived in the U.S. (settling in Pennsylvania) in 1910. She married my great-grandfather (who arrived in the US from Slovakia in 1907) in 1911. Most of my ancestors in Pennsylvania were coal miners. You can see some insignias, although they are quite blurry, on some of the men's uniforms in this photo...that I think could help identify what group they were a part of and thus help us figure out which of our ancestors this is a photo of. Can anyone help with ideas about this photo?

Here is a link to the image: https://drive.google.com/file/d/1K_B0UjAsskN-Npgdyw5aoMWCqqWOX4FB/view?…

Thanks in advance for any help or insights!
