浅析井下三角高程测量限差

Discussion on the error bound of underground trigonomertrical leveling

采用线性回归分析的方法 ,结合庞庄煤矿实际 ,对井下三角高程测量的限差进行了详细分析 ,并针对《煤矿测量规程》的不足 ,提出应结合矿井实际制定合适的限差要求 ,对随采区控制导线布设的三角高程测量 ,应按路线倾角来制定相应的限差要求 .

Based on the situation of Pangzhang coal mine, the error bound of the underground trigonometrical leveling has been analyzed by the method of linearity regression analysis. It has put forward the appropriate requirement of error bound due to the un_satifactory of the regulations of coal mine survey. The distribution of control conductive wires in mining area of the trigonometrical leveling survey should be made according to the dipangle of the lines.
