ABSTRACT
The main objective of researches was the analysis of experience of application of
technological schemes of mining of longwall panels without re-installation of the
equipment of a coal face. For conditions of the mine Taldinskaya-Zapadnaya-2
change of coal face output when mining longwall panels with a longwall turn is
shown. Sharp decline in output of a longwall at a face turn is shown. Comparison of
efficiency of mining of longwall panels with a turn of a complex and at re-installation
of a longwall is executed. Recommendations about decrease in equipment downtimes
and increase in efficiency of re-installation of the equipment of a longwall are made.
Key words: underground mining, coal mine, longwall, face equipment, downtime, reinstallation, removal, efficient, output

1. INTRODUCTION
Longwall mining is the main a method of underground coal mining in Russia. Application of
longwalls ensures high cost efficiency and safety of coal mining. The majority of the Russian
mines is equipped only with one completely fully-mechanized longwall that provides the
minimum quantity of entries in the mine and the minimum costs. However, during the periods
of outages of a longwall face coal mining in the mine is not conducted, but need to carry out

ventilation and a water outflow remains. Long outages of the high-performance equipment
can cause a significant economic disbenefit to the mine. One of the longest processes at
longwall mining is removal, transportation and equipment installation after completion of
works on one longwall panel and transition to mining of the following longwall panel. With
the planned duration of re-installation of the equipment of 40-60 days the actual outages of a
face can reach 150-300 days. The high duration of works on re-installation of the equipment
is connected with the fact that both main methods of conducting dismantling works (carrying
out the recovery room in advance and forming of the recovery room a longwall), are
characterized by influence of the increased rock pressure around the recovery room and low
roof stability of recovery rooms that significantly complicates process of removal of the
equipment [1-10]. The increase in productivity of longwall faces has led to reduction of time
of mining of reserves of one longwall panel and the share of time for remounting constantly
increases. Also it should be noted that geological and mining factors have a considerable
impact on the production rates of a longwall face [11-26] many. Output of a longwall face
also depend on stability of longwall gateroads. Technological schemes of mining of longwall
panels without re-installation of the equipment have been developed for decrease in outages
of the longwalls caused need of re-installation of the equipment of a longwall face [2, 7, 28,
29]. The developed technological schemes are recommended first of all for mining of sites
with limited sizes where as a result of small volumes of reserves and long terms of reinstallation, application of mining plans with peremontazhy can be economically inefficient.
Experience of mining of several longwall panels without re-installation of the equipment is of
interest actual.
2. METHODS
When holding researches the analysis of change of output of a longwall when mining seam 70
in the mine "Taldinskaya-Zapadnaya-2" in the conditions of the Kuznetsk coal basin was
made. Seam 70 has the average height of 4.6 m. An immediate roof of seam – aleurolite
(thickness of 2.5-8 m). A main roof of seam – sandstone (thickness of 9-20 m). Depth of
works on the longwall panels 70-02, 70-03 and 70-04 fulfilled without re-installation of the
equipment of a longwall was from 90 to 150 m. Longwall panel width changed from 170 to
250 m. Total length of a longwall panel reached 5000 m. Reserves of coal within the longwall
panel exceeded 6.8 million tons.
3. RESULTS AND DISCUSSION
The analysis of change of longwall output when mining longwall panels 70-02, 70-03, 70-04
(figure 1) taking into account work in the period of a turn of a face and at a face advance
without turn.

Mining of Several Longwall Panels without Re-Installation of Equipment of Coal Face: A Case Study
Figure 1 Mine layout designed for mining longwall panels without re-installation of the equipment
Figure 2 shows evolution of an output on a longwall. It is visible that during re-installation
of the equipment from the longwall panel 70-02 on the longwall panel 70-03 decrease in
mining of a longwall by 30% was observed (from a mean 157,000 up to 113,000 tons a
month). The following the turn was carried out with the increased panel width and
characterized sharp (for 60%) by decline in output of a longwall (from 155,000 to 60,000 tons
a month). Such significant decline in output has led to increase in duration of a turn up to 12
months.
Figure 2 Evolution of longwall output (longwall panel mining with turn of longwall)
Thus, application of a turn of a longwall in the mine Taldinskaya-Zapadnaya-2 has led to
significant decline in output of longwall faces. For assessment of economic consequences, the
schedule of dependence of estimated production rates of a longwall at application of a
technological scheme without turn has been constructed – with re-installation of the
equipment of a longwall (figure 3).

Figure 3 Evolution of longwall output (longwall panel mining with equipment re-installation)
Figure 3 shows that even in case of long re-installation of the equipment (3 months)
duration of mining of sites would be 4 months less, than in case of a longwall turn. Thus, the
analysis of experience of a turn of a complex in the mine Taldinskaya-Zapadnaya-2 has
shown its low performance. The economic disbenefit from increase in terms of mining for 4
months makes about 10 million US dollars.
4. CONCLUSIONS
As a result of the researches executed in the conditions of the mine Taldinskaya-Zapadnaya-2
decline in output of a longwall when mining longwall panels without re-installation of the
equipment is established essential (for 30-60%) (with a longwall turn). The analysis of
possible duration of mining of reserves of longwall panels 70-02, 70-03, 70-04 has shown a
possibility of reduction of terms of their mining more than for 4 months. Thus, the selected
way of decrease in equipment downtimes can be considered inefficient. For increase of output
of longwall and decrease in outages during the periods of re-installation we offer by
improvement of re-installation based on forming of the recovery room by a longwall with
application of a mine grid and roof bolts.
