六十年代以来,随着地质勘探工作的进展,相继查明了一些大型的褐煤田,这些褐煤田储量大,埋藏较浅,复盖层较松软,有可能采用轮斗铲采掘、皮带运输、排土机排土的连续开采工艺进行露天开采。为了进行开采工艺的选择和轮斗铲设计的基础数据。根据几年来对现场试验和室内试验的观察与分析,岩石的切割阻力与岩石的力学性质、构造特征、切割参数及速度、斗齿形式和斗
Since the 1960s, with the progress of geological exploration work, some large-scale brown coal fields have been identified one after another. These lignite fields have large reserves, shallow burying and relatively soft overburden. It is possible to adopt bulldozer shovel mining, belt transportation, Dredger earthwork continuous mining technology for open pit mining. In order to carry out the selection of mining technology and shovel shovel design of the basic data. According to several years of field tests and laboratory tests observed and analyzed the cutting resistance of rock and rock mechanical properties, structural characteristics, cutting parameters and speed, bucket teeth form and bucket
