开滦煤矿赵各庄矿开掘深度已达到-1100米,东西走向8300多米,又因巷道布置为阶段石门式。主要运输道与石门,石门与回风道,纵横交错,风流方向如不控制很难达到拟定的效果。所以控制风流的建筑物风墙、风门、风桥等非常重要。我矿通风区试验一种无木框砖风门,经过三年多的实践已证明非常适用于井下压力不太大、永久性的不经常过车的石门、回风巷道内,既节约了木材又减少了维修工作量。
Kailuan Coal Mining Mine Zhao depth has reached -1100 meters east-west to more than 8300 meters, and because of the roadway layout for the stage Shimen. The main transport lane and Shimen, Shihmen and return air duct, criss-crossing, romantic direction, if not controlled is difficult to achieve the desired effect. Therefore, the wind flow control buildings, wind doors, wind bridges and other important. I mine ventilation zone test a wood-free brick air damper, after more than three years of practice has proved very suitable for underground pressure is not too large, permanent infrequent car door, return airway, which saves both wood Reduce the maintenance workload.
