_____________________Xinhua news agency said the landslide covered three square kilometers of about two million cubic meters of dirt early Friday morning, burying a worker's camp at the mining site about 870 kilometers east of Lhasa, the Tibetan capital. Search efforts are being hampered by continuing smaller landslides, the 4,600-meter altitude and below freezing temperatures which are affecting the abilities of the search dogs. More than 2,000 rescuers have been dispatched to the area. ______________新华社消息,在周五早上,滑坡导致200万立方米的淤泥覆盖了3平方公里的区域,同时也掩埋了矿区附近工人的营地,该矿区位于西藏省会拉萨870公里处.搜寻救援工作被连续不断的小型塌方阻断,4600米的海拔和零下的温度也影响了搜救犬的能力.超过2000名搜救人员已经被派遣到这一区域.
