自卸汽车运输由于机动灵活,对各种地形条件适应性较强,投资少等优点,在一些露天矿山中获得了广泛的应用。本文仅就高原地区的白银露天矿的重型自卸汽车发动机使用情况,谈些粗浅的看法。甘肃白银公司露天矿由折腰山矿床(一采场)、火焰山矿床(二采场)组成。地处甘肃中部,海拔标高约1900米,属于大陆性气候,水源缺乏,干旱多风,年温差和昼夜温差大,年降水量202毫米左右,而蒸发量却达2048毫米,为降水量10倍之多。 Dump truck transport has gained wide applications in some open-pit mines because of its flexibility of maneuvering, strong adaptability to various terrain conditions and less investment. This article only on the plateau area of ​​silver open pit mine heavy-duty dump truck engine usage, talked about some superficial view. The open pit mine of Baiyin Company in Gansu Province consists of the Yaoxishan deposit (a stope) and the Huoyueshan deposit (two stopes). Located in the middle of Gansu, elevation of about 1900 meters above sea level, belongs to the continental climate, lack of water, drought and windy, annual temperature difference and temperature difference between day and night, about 202 millimeters of precipitation, but the evaporation is up to 2048 millimeters, 10 times precipitation Much.
