New posibilities of solving the stability mining of mining workings in conditions of the Novaky mine
Abstract
The stability of mining working is currently an important aspect which becomes a part of their production. The quality of a mining working affects tension and deformation states of the completely mechanical coalfaces. When taking retrogressive geological characteristics of exploited mining fields into consideration and comparing them with these in the past that it is necessary to solve the steadiness of shafts in order to balance the tension influence. The shafts should remain functional during their period of service without needs for repairs. As all repairs are performed manually, they increase the expenses per one ton of coal. They also influence the movement of coalfaces as well as the stability of pillar.
