METHOD OF DETERMINATION OF BOUNDARIES OF DEPOSIT HAZARDOUS SHIFT ZONES |
摘要 |
mining, particularly, mine surveying. SUBSTANCE: method includes setting of bench marks on main profile lines and additional profile lines. Main profile lines are located along and across the strike of separate deposits within field boundaries. Additional profile lines are located in zones of effect of mining operations. Point of intercrossing of main profile lines are connected by additional lines by which bench marks are set to form single system of profile lines. Shifts of bench marks of single system of profile lines are continually observed. Results of sail observations are used for construction of isohypses of earth surface subsidence. Boundaries of zones of hazardous shifts are determined by character of change of isohypses. EFFECT: higher efficiency of determination of boundaries of hazardous shifts within boundaries of fields covering several deposits. 2 dwg
