Conclusions

  1. 1.

    A geotechnical method of coal extraction must be chosen by taking account of the possibilities for its combined processing and utilization in the national economy.

     
  2. 2.

    The final decisions to use any particular geotechnical method can be made only after an economic assessment of its advisability, e.g., with the aid of an economic-mathematical model; such a model is outlined in general in the above article.
