According to the theory of yielding supporting,the authors introduces the combination of the half-circle bamboo lagging and steel trapezium-shaped support together with welding antiskid device at the structure of steel trapeziumshaped booth beam and lag winch's joining section,which optimizes the structure of the steel trapezium-shaped support.
根据可缩性支架原理,半圆竹背板与矿工钢梯形支架配套使用,并在矿工钢支架棚梁和棚腿铰接处焊接防滑装置,以优化矿工钢梯形支架结构。
The safety monitoring of mine devices, especially mine hydraulic supports, develops at a low pace which has been unable to adapt to increasingly complex exploitation environment.
但长期以来,煤矿安全状况一直是制约煤炭工业发展的重要因素,矿用设备特别是矿用液压支架的安全监测发展十分缓慢,已经无法适应越来越复杂的开采环境。
