In order to improve the lump coal rate in the big gun adopts the surface, through four blasting scheme comparison, select split-second delay blasting scheme of slope hole of minor diameter medicine finally, and carry on theory analysis to its parameter and test on a small scale.

The development and application of QXY-5 memery borehole inclinometer;

The application of borehole inclinometer in the monitoring of accumulation body's strain

Based on the windows operation system, using the object-oriented programming Language-Visual Basic and the object-oriented database management and development system-Access, automatic handiling and analysing program of borehole inclinometer has been developed.

On the basis of analysing monitored information of boreholes of seven hydro-engineerings and twenty-seven rock-slopes and landslides obtained by borehole inclinometers,the forms of deep deformation curves may be at least divided into four kinds of curves in category,i.

The effect of inclinometers for slope monitoring of No.1 Landslide in Tangjiao Village

Field observation methods, including inclinometers and surface deformation monitoring networks, have been used to monitor the stability of the landslide before and after inpoundment of the reservoir.

The structural principle of inclinometer and its application to slope monitoring for Three Gorges permanent shiplock are described briefly .
