This text is through surveysing and exploits practice with the coal to SONGZAO COALMINNING BUREAU,SHIHAO COAL MINE' s east wing rich water district. At corrosion moisture rock strata lead swimming skill,underground river survey and coals under corrosion mositure rock strata rxploit method technology go on and study safely,Its overall train of thought is:Adopt many kinds of karst project things and visit the means of reconnoitring,the space form to the moisture body of corrosion is surveyed,Find out underground river route of flowing through and distribute law and mend source of water is then not at different rock quality,inclination and exploit to brave and fall and bring and lead water analyse by height who crack bring methods,Determine and work Taxi assign scheme,besides,take the corresponding safe precaution measure in the course of exploiting. The overall train of thought studied is:Adopt many kinds of karst project thing and visit the means of reconnoitring,the space form to the moisture body of corrsion is surveyed,Find out underground river route of flowing though and distribute law and mend source of water is then not at different rock quality,inclination and exploit ot brave and fall and bring and lead ink highly bring by crack methods,Analyse and determine and mine and work. Taxt assign scheme,besides,take the corresponding safe precaution measure in the course of exploiting.In order to achieve the purpose that the security exploist,this text starts with from studying the forming of the karst and characteristis of the corrosion rock stratum,It pass resistances lead sectionses by lawses,Statics a nip law,Natural electric field select frequently law,Very low frequency electromagnetism law,Charge law,Fyequency electromagnetism law,Automatic resistivity law and drilling,hole radio perspect,pressure pulse interfere the scenes of means test and interfere laboratory simulated test each of testing etc with pressure pulses,Set up geological reduced scale model and automatic data and gather the system,use broad sense to deal with surveying the materials the short burst of theories,Use grey systematic theorieses analyse and appraise model result of the test and use limited unit go on and well up water yield calculate and wait for by law,Having clarified the moat rich hydrogeical situation of water district of east wing of colliery of stone,at the same time,Visit the method to reconnoitre to applied to the project thing of karst to validity and dependability that the reconnoitres the means optimum association way under different periods,different geological conditions.Fall and bring and lead water survey and prove by "two talps" height who crack bring braving,the ground holes and constructs to observe methods to determine the high method of brave and fall and bing and lead ink bing by crack feasibly. Through drawing core appraise,adopt and "hole and develop liquid leak person who loss" law observe and develop to leak person who lose and water level change in holing and creep into the unusual situation liquid,Analyse up,Give and judge that brings the degree of difficulty,so,should cooperate with other means to analyse in surveying at the scene.At last,this text at colliery of SHIHAO east wing rich water district of No. 1612 and No. 1812 tests,Survey the result to the karst and "two talps" highly verify,At the same time moisture rock stratum assign and "collapse completely method" rationality and prevent and cure water study by the validities of measure that exploit by lower coal faces to corrosion.
