摘要
本文介绍了一种对于不同支护型式的巷道,应用相应的矿压观测仪器,间接地测定出P-U曲线的方法,及该法在铁法三台子矿的具体应用。
The roadway P-U curve deduced theo-retically from mechanics model is difficult to coin-cide with the field data, and the measurement ofthe curve in situ by means of the bore-hole defor-mation instrument can only be applied in soft rock.For this reason an indirect method measuring thecurve in roadways with different supports is intro-duced, which uses the strata pressure instruments.By applying the method, the instrumentation of thecurve at Santaizi Colliery, Tiefa Coal Mining Bu-reau, is described.
