西华山钨矿共有8个溜矿井,17个卸矿峒室。这些溜井的卸矿峒室均设在各中段主要运输平巷附近,其中绝大部分位于进风巷道的旁侧。由于各个溜井服务的中段数多,卸矿频繁而且量大,对溜井空气柱起着强烈的冲击压缩作用,带出大量的矿尘,使卸矿峒室周围的粉尘浓度多在3～4毫克/米~3以上,有时竟高达20毫克/米~3,严重地污染了井下新鲜风流。 West Huashan Tungsten mine a total of eight slipped mine, 17 dumping room. The chute wells are located near the main transport lanes in the middle section, most of which are located beside the air intake tunnels. Due to the large number of middle pitches of each chute service, frequent and large dumping operations play a strong impact and compression effect on the air column of chute wells, resulting in a large amount of dust and dust. The concentration of dust around the dumping chute is 3 to 4 milligrams / M ~ 3 or more, and sometimes as high as 20 mg / m ~ 3, seriously contaminated the underground fresh romantic.
