摘　　要：弹簧闸制动系统是矿井提升机的重要组成部分。建新矿主井绞车为双滚筒缠绕式,斜井提升,采用角移式重锤制动方式,机械杠杆环节多,维修量大,而且制动灵敏度差,无二级制动,2009年元月我们通过改进,选用块式弹簧闸制动装量,实现了双线制二级制动。使绞车的制动系统更安全、灵敏可靠。Spring braking system is an important part of mining hoist. Host well hoists in our colliery are double drum winding type, inclined shaft hoisting. Using angle moving hammer braking mode, many links of mechanical lever, large maintenance, poor brake sensitivity and no 2--layer braking would occur. On January, Z009, through improvement, block spring braking equipment was chose to achieve double line 2--layer braking, which made spring braking system more safe, sensitive and reliable.
