영문 초록

A various kinds of harmful gases in the gallery and the increasing quantity of in-flow water are the important factors causing mainly the decline in production. In this thesis, the increase and decrease of in-flow water which effects the out put have been investigated and analysed in the statistical method. Through the results obtained together with the stastistical data some typical interreation formula between the quantity of in-flow water and production have been induced and the productive percentage in season was examined with special reference to Changsung Coal Mine. The formulas are as fallows: (1) Underground in-flow water to production; Y=-5.74x²+108.9x+6,346.6 where, Y: production(tons/day): x:in-flow water(m³/min), (2) Rain and Snow fall to production; P=6.555-1.591 R+1.282S where, P;production(tons/day); R:rain fall(mm); S : snowfall(cm), (3) Productivity ratio in season compared with the average annual production; 1st quarter of year:100.1%, 2nd quarter of year: 100.3%, 3rd quarter of year: 97.2%, 4th quarter of year: 102.4%.
