Reliability Analysis Of Mining Survey Achievement

Along with national economy high speed development, the country increases day by day to the coal mine resources demand, But follows closely the ore difficult to occur repeatedly has all sounded the alarm bell to us, Meanwhile also more and more takes to the resources mining security, The paper mainly from the mining survey angle, is the safeguard mine production security, systematically studied, has discussed the survey achievement reliability and the guarantee measure.Through relations which distorts to the central meridian and the projecting plane choice and the projection, Elaborated how the mining area independent coordinate system does establish reasonably under question as well as in guarantee graph material requests and so on exchange investigation, Mining area independent coordinate system and national coordinate system transformation.When control survey, must unite measured some national or under the place coordinate system spot achievement begins reckoning the spot, But the association measured these will begin reckoning a compatibility not to be good affects the precision of the entire net, Therefore we in join the association measuring point time the control net adjustment should to carry on the analysis to its compatibility, rejects in them the compatible not good spot, increases the control net precision.The mining settlement research and the application and the survey achievement reliable or not have the very big relations, Introduced several kind of possibilities create mine the harm indirect influence the situation and the countermeasure.The paper embarks from the practical work, And so on has carried on the detailed discussion to the control net reliability and the efficiency appraisal and the gyrotheodolite in mine penetration survey application and the direction wire net strict adjustment method.
