摘要
寺河煤矿原使用ZY12000/28/62型液压支架,由于开采条件变化,需要增加支架支护高度。受提升运输条件的限制,支架宽度保持不变。通过分析计算,论证ZY12000/31.5/70D型支架的稳定性,并提出了保证支架稳定性的措施。
Due to the change of mining conditions, the supporting height of primary hydraulic support （ ZY12000/ 28/62 type） needs to be enhanced. By the restriction of hoist and transport conditions, the width of the new support （ZY12000/31.5/70D type） remains that of the old one. Analysis and calculation verifies the steadiness of the new support and proposes the measures for support steadiness.
