The paper discussed the design principles of compatibility,expandability,dustproof,shockproof,dampproof and low power consumption of mine-used I. S. computer,and analyzed the technical problems of realizing the mine-used I.
Application of dust proof and extinguish technology for π fall roof working surface by injecting water and high pressure,drilling in two tunnels and spraying of MgCI2 to soft ect. coalwall face,are discussed.

The evaluation results were as follows: The working environment has shown distinct improvement after taking ventilation and dust control measures. The dust concentration which was 31.4mg/m~3 in the 1950s was reduced to 3. 4mg/m~3 in the 1980s.
Methods (1)To forecast pneumoconiosis patient number and pneumoconiosis patient death number reduced owing to dust prevention with grey dynamics model,GM(1,1).
