黄土丘陵沟壑区煤矿排矸场往往选择在沟道中,而该区水土流失主要产生在沟道,建设中对排矸场的水土流失防治要求较高。沟道中的排矸场因位置、排矸工艺选择的不同,其水土流失防治措施要求也不相同,要根据实际情况布设拦挡坝、截排水系统,并进行坡面整治。 In the loess hilly and gully areas, coal gangue dumping sites are often selected in trenches, while soil and water loss in the area mainly occurs in trenches, and soil and water loss prevention and control of waste dump sites are required to be higher during construction. Due to the different location and gangue selection process, the drain prevention and drainage measures in the trench are not the same. The dam, drainage and drainage system should be laid according to the actual situation and the slope surface treatment should be carried out.
