一、前言 胶带作为运输的手段已广泛应用在矿山的地面和井下。随着采掘深度的加大,生产能力的提高,胶带输送机正向高速化、大型化发展。虽然采取了种种防火措施,但运输胶带的燃烧、熔断及火灾事故仍不断地发生。由于许多胶带在矿井的进风巷内连续设置,一旦发生火灾,就迅速蔓延,含有有毒有害气体的高温气流、烟雾沿着巷道流动,往往导致极其重大的事故。1950年英国Creswell煤矿的胶带火灾致使80人死亡。1984年1
First, the foreword Tape as a means of transport has been widely used in the mine ground and underground. With the deepening of the digging, the improvement of the production capacity, the belt conveyor is speeding up and the large-scale development. Although various fire prevention measures have been taken, the burning, blowing and fire accidents of transportation tapes continue to occur. Due to the continuous arrangement of many tapes in the air intake in the mine, the rapid spread of fire in the event of a fire, the flow of hot air containing toxic and harmful gases and the flow of smoke along the roadway, often result in extremely serious accidents. The tape fire at the Creswell mine in England in 1950 caused 80 deaths. 1984
