波兰在广泛推广锚杆固定井筒装备部件的方法。1966～1967年间,这个方法成功地应用在《赫瓦罗维兹》等矿井建设中,这些井筒采用的是由CT3_c钢制成的充填水泥砂浆的楔形锚杆,锚杆直径30毫米,长300～400毫米。
Poland is in the process of widely promoting bolt-fixed wellbore equipment components. From 1966 to 1967, this method was successfully applied to the construction of mines such as “Hvarovitz”. These shafts were made of CT3_c steel filled cement mortar wedges with a diameter of 30 mm and length of 300 ~ 400 mm.
