Presently, mobile diesel equipments contribute a lot to improve the economic feasibility of underground mining and tunneling operations. Even in Korea, a lot of diesel equipments are being applied to the undergroud workings already, but the technology of management and control of them is not sufficient yet. This study handled the production procedure, characteristics and evaluation technology on diesel particulate matte(DPM) which is known as a carcinogen. For easy measurement of DPM using laser dust monitor, conversion known as a carcinogen. For easy measurement of DPM using laser dust monitor, conversion factor(k) to gravimetric concentration has been acquired. It is appeared that the critical material among the diesel exhaust pollutants is becoming DPM instead of NOx from this year of 1996 according to the Government regulation.
