一、引言 安德森、斯特拉斯克莱德公司(以下简称AS公司)巴托克爬底板采煤机的第一台样机于1976年1月在英国煤矿投入生产。随后又使用了两台采煤机以便评价这种新型采煤机在各种地质条件下适用范围及其潜力。 在巴托克采煤机初步试验成功后,已有10台采煤机在厚度864毫米至1270毫米的不同煤层里使用。还有10台采煤机不久即将投入使用。巴托克采煤机在很短的时间内就被 I. INTRODUCTION The first prototype of the Bartok crawler shearer from Anderson, Strathclyde Company (hereinafter referred to as AS Company) was put into production in January 1976 in British coal mines. Two more shearers were later used to assess the scope and potential of the new shearer under various geological conditions. Following the initial success of the Bartok coal winning machine, ten shearer mills have been used in different seams with thicknesses of 864 mm to 1270 mm. There are also 10 shearer will soon put into use. Bartok coal shearer was in a very short period of time was
