摘要/Abstract

摘要： 为获得合理的采空区强制放顶爆破方案,根据上覆岩层的急倾斜性并伴有水平裂隙发育的实际情况,设置两组方案。通过爆破点设置范围不同,产生不同的爆破方向和爆破范围。分析上覆岩层运移和爆破产生裂隙的发育特点。爆破后上覆岩层运移范围较大,可发展至地表。横向爆破方案塌落影响范围较宽;而纵向爆破方案塌落影响范围较窄。横向爆破方案爆破后地面沉降深度比纵向爆破方案的地面沉降深度大20%。

Abstract: According to the actual situation of overburden steep inclined strata with horizontal fracture, the reasonable goaf forced caving blasting schemes are studied. Considering overburden characteristic and representative, two schemes are put forward with the attachment perpendicular to their break point locations. By setting different places of blasting points, the different directions of blasting and blasting area are determined, and the overlying strata movement and development characteristics of blasting fracture are analyzed. The overlying strata movement range is larger and can develop to the surface after blasting; The conclusion is that the influence range of the fracture is wide in the level blasting scheme, while relatively narrow in the vertical blasting scheme; the ground subsidence of the level blasting scheme is 20% larger than that of the vertical blasting scheme.

Key words: Mining engineering, Steep overburden, Horizontal fracture, Forced caving blasting, Simulation
