Elimination of safety risks at mined Coal faces in the paskov mine, Staříč plant- OKD, a.s. Czech Republic

Abstract

The contribution deals with the satisfaction of operating and safety conditions during the mining of coking coal at faces endangered by coal and gas outbursts in the Paskov Mine – Staříč Plant. Underground in the mine, methane-air mixtures and coal and gas outbursts represent a high hazard. To enable mining operations at these faces at risk of this hazard, detailed knowledge of geological conditions, technical and operational data on mined faces, degree of influencing the overlying and underlying strata of the seam being mined, and a possibility of utilization of degasification as well as outburst prevention are required. These facts influence in the highest degree safety risks at mined faces. The article informs about an engineering solution for the ensuring of mining operations at the faces No. 084 271 under conditions of high emission rates in the joint-stock company Paskov Mine – Staříč Plant, OKD, a.s.
