Abstract:

The article points out the shortcomings in the labor arrangement at the 11th long wall. The analysis results have shown: (i) The actual number of employees assigned to use is often much higher than expected. It is because Ha Lam Coal Joint Stock Company only designs for good conditions, but actually, the company faces many obstacles due to the characteristic production conditions; (ii) the actual productivity is much lower than the designed labor productivity because the calculation of the number of employees is not consistent with the production conditions of the long wall; at the same time, the number of manual workers for ancillary work is too much arranged according to actual needs; (iii) The current level of direct labor productivity at the 11th long wall is still low compared to the actual capacity, not motivating workers to increase labor productivity. The solutions to overcome the problems are (i) Complete the calculation of the number of employees considering the specific production conditions and the number of auxiliary workers; (ii)Re-arrange labor in manual auxiliary production to reduce labours; (iii) Recalculate the direct labor productivity assigned to the 11th long wall. With these solutions, the company will increase the initiative in production, improve labor productivity and lower product costs.
