摘 要:色连二矿1312(2)工作面上覆基岩较薄,初次来压和周期来压期间支架有被压架的可能。通过KJ216型支架监控系统对该工作面支架实时数据监测,统计出工作面初次来压步距、周期来压步距、动载系数、初撑力与循环末阻力的利用率以及相互关系等矿压数据,表明ZZ10800/22/45型四柱支撑掩护式支架能够适应1312(2)工作面回采要求。The overburden rock on the work face in 1312 (2) Selian No.2 Colliery is quite thin, as a result, there is possibility of pressurizing of hydraulic support during the period of first weighting and periodic weighting. Through KJ216 support surveillance system, the real-time data of the support in the work face can be monitored. Thereafter, the mine pressure data, such as the first weighting step distance, the weighting step distance, the dynamic load coefficient, setting load, the utilization ratio of the end-circulation resistance, and the interrelationship can be counted out. The data shows that the ZZ10800/22/45 four pillar support and shield type can meet the requirement of 1312(2) work face.
