采深已达1500米的十月矿床,其开采过程与寻求和普遍采用能排除矿体边缘部分岩爆危险的工艺相结合。而且随着开采深度和采空区跨度的加大及回采强度的提高岩爆问题也越来越严重。大量的断层、逆断层和平移断层限定矿体呈阶梯状结构,并决定超过γH地质构造应力场的存在。第1级和第4级构造块的取向近于子午线方向,并与沿倾斜和逆倾斜从中 The mining of the October deposit, which has reached a depth of 1,500 meters, has been combined with the search for and widespread adoption of techniques that eliminate the danger of rock burst at the margins of the body. With the increase of mining depth, the span of goaf and the increase of recovery strength, the rock burst problem becomes more and more serious. A large number of faults, reverse faults and translatory faults limit the orebody to a stair-like structure and decide to exceed the existence of the γH geological tectonic stress field. Tier 1 and 4 building blocks are oriented closer to the meridional direction and from the slopes and reverse slopes
