【正文】 eformation and slope location and the elevation. Deformation appears. (3) Slope x, y to the total displacement than its z displacement, and X, y to the average annual rate of less than slope displacement settlement rate, the smaller slope settlement. (4) x, y, z three days to an average annual rate of displacement experienced far less than the value of early warning mm / d. (5) From the regression analysis, x, y, z three to the total displacement has stabilized, slope landslide occurred less likely. 3, blasting vibration monitoring and security [6 ~ 8] blasting parameters optimized design Engineering geological conditions in certain circumstances, Mine production of various blasting vibration is high and steep slope against the main factor for stability, especially in the more fractured, broken with the development of slope especially 2 Daye Iron ore hanging wall of the former mining stope under high steep slope, Due to F13 Faults intersected ore, coal blasting to ensure high steep slope stability, we must adopt damping control blasting technology to optimize the blasting parameters, to minimize blasting vibration hazards. (1) inline realm, conditional use presplit blasting to the formation of a crack, blasting seismic wave barrier to the spread of Rock reservation. With smooth blasting, blasting possible weakening of the reservation slope hazards. 12 (2) strictly control the production of a major blasting largest drug production and logistics and fireworks up small to effectively control the guns blasting hazards。 ② use of monitoring information control blasting scale, optimize the blasting process, correctly production and ensure slope stability. blasting vibration monitoring Blasting vibration monitoring will include surface particle velocity, displacement, acceleration, and so on. Due to the steep slope stability and particle velocity is most closely related, therefore, The monitoring of the content of the particle velocity, which is currently carrying out the most mon and most works on monitoring the content. (1) Testing system. Blasting vibration test more power measurement method. It uses magic sensor in the relative movement, and vibration have a certain ratio between the signals, after secondary instruments and recording devices to be vibration signal. 13 (2) Monitoring instruments. Chengdu Branch using dynamic equipment developed and manufactured by Limited IDTS 3,850 blasting vibration device, with a CDa seismometer connected placed in a testing point. Test, triggering shock vibration signal instrument will record it automatically simulate voltage conversion to digital storage, these data can be stored for a long period, even after the blackout began will not be lost. After blasting through an RS 232 serial port with the standard notebook puter munications, puter waveform, spectra of the various parameters and test results form the display, storage and printing. (3) Measuring point distribution. Taking into account the impact of F13 fault, according to the topography of mine, the following measuring point distribution program : section of the fault on F13 layout measuring point two, F13 fault runs through 2 orebody, Blasting inevitable because of the slope stabil
