Coal mine hit again by explosion - is a cover up taking place?

Ruda Slaska based Bielszowice coalmine, where 17 miners were seriously injured in a methane explosion on Monday was again quaked by another blast yesterday. The incident took place in the same area as on Monday, but this time the rescue team working at the site was evacuated just in time to remain unscathed. According to Polish Radio Information Agency (IAR) the second explosion might have been "deliberate" to destroy evidence of M onday's incident in face of the ongoing investigation into the case. The incident resulted in media speculation that the vein in question was being mined illegally as it had been closed down. The press conference with the State Mining Authority (WUG) scheduled for yesterday was cancelled without any explanation and so far it has refused to disclose any details about the incident.
