沙坪煤矿18206综采工作面过空巷支护技术研究

Study on Support Technology when Crossing Empty Roadway in 18206 Fully Mechanized Working Face of Shaping Coal Mine

针对沙坪煤矿18206综采工作面过空巷存在顶板压力较大、 支架工作阻力变化复杂等问题,结合沙坪煤矿18206综采工作面实际情况,提出了综采工作面过空巷支护技术方案,并对空巷的补强支护和过空巷前后的矿压分析进行研究,通过现场支架工作阻力和空巷顶板下沉量来衡量空巷的支护质量,确保工作面安全顺利地通过空巷.

When crossing empty roadway in 18206 fully mechanized mining face of Shaping Coal Mine,there are large roof pressure and complex change of working resistance of support,combined with the actual situation of 18206 fully mechanized mining face in Shaping Coal Mine,the reinforcement support of empty roadway and the analysis of mine pressure before and after crossing empty roadway are studied,and the supporting quality of empty roadway is measured by the working resistance of support and the roof subsidence in empty roadway,so as to ensure the working face crossing the empty roadway safely and smoothly.
