普里阿尔贡斯克矿山化工公司各矿都在采用将矿块分成2～3个同时开采的分段和下向水平分层充填法连续回采方案开采急倾斜矿体。众所周知,这种开采顺序与矿山冲击地压规程规定的有冲击地压危险矿床的全面无矿柱安全开采法概念相抵触。解决这种矛盾的唯一方法,是在这种连续回采工艺中推行逐渐削减矿柱应力极限增长阶段有效控制地质力学状态的方法。在安泰(AHTreй)矿床500m深处采取逐渐减小矿柱冲击地压危险的预防措施完成了双分段连续回采急倾斜矿体的试验。 6a矿体为厚0.5～20m亚子午线走向的急倾斜矿体岩系。由于该矿床的成因特点,脉状、网状矿体都赋存于160、161、13号急倾
Each mine in the Puri-Arnonskaya Mine Chemical Company is mining a steep orebump using a continuous mining scheme that divides the nugget into two or three simultaneous mining sub-stages and a horizontal sub-level filling method. It is well-known that this sequence of mining contradicts the concept of a comprehensive non-pillar safe mining method of rockburst dangerous deposits under the provisions of the mine rock burst regulations. The only way to deal with this contradiction is to implement a method of effectively controlling the state of geomechanics in this continuous recovery process by gradually reducing the stress during the ultimate growth of pillar stress. At a depth of 500 m from the AHTreй deposit, a trial of double-section continuous recovery of the steep-inclined ore body was completed with precautionary measures to reduce the risk of rockburst. The 6a ore body is a steep-dipping ore body that is sub-meridional 0.5 ~ 20m thick. Due to the genetic characteristics of this deposit, veins and reticular orebodies occur in sharp dip at 160, 161 and 13
