众所周知,倾斜中厚矿体(倾角30～35°、厚度4～10米)由于产状和赋存条件不利,往往难以找到理想的采矿方法。近些年来,随着无轨自行设备的推广以及锚杆支护、深孔凿岩等技术的不断发展,倾斜中厚矿体的开采技术也取得了较大进展,一些新的采矿方案相继出现(表1),其中尤以分段房柱法应用较广,效果较好。
It is well-known that it is often difficult to find the ideal mining method due to the poor occurrence and occurrence of moderately inclined ore bodies (dip angle 30-35 ° and thickness 4-10 meters). In recent years, with the promotion of trackless self-propelled equipment as well as the continuous development of technologies such as bolt support and deep hole drilling, great progress has been made in the mining of inclined medium thick ore bodies, and some new mining schemes have emerged Table 1), especially in the wider section of the column method is widely used, the effect is better.
