Wiremess is 50 mm x 50 mm. While drill bit size is 43 mm There is no problem 😊 drilling through wiremess. It's might be first time in mine, that's why drillers are opposing.

Dear Sir
Our experience is there is no problem in drilling through the mesh with pneumatic or hydraulic roof bolters.

Dear Members,I want to know the best procedure to install wire mesh in a coal roof having slips. The roof is already supported through roof bolts.Doesn't opening the existing roof bolts to secure the mesh weaken them ?Is fresh bolting the only way to secure it ? Coz the drillers say they have problems getting their drill bits through the mesh.
