Coefficient of correlation for the given equation is 0,88±0,016.
Accordingly, it was established zone sizes of ground compaction by
using aluminum hydroxide solution depending on angle of ground contain-
ment of trench charge outburst.
According to the results of experiments in the industrial conditions and to
the statistical treatment of the results, which are given in fig, 2-5, the method
of engineering calculation for sizes of compaction zones in the exploration of

flowing grounds
by exploring of trench charge outburst using surface active
substances solution.
1. Sizes of compaction zone of flowing ground on upper butt by charge of
outburst with using surface-active substances (aluminum hydroxide) depend-
ing on angle of ground containment. It is calculated by the following formula:
,
m
(5)
k – coefficient, which takes into account the level of ground compaction of
exploring mass: for fine grain sand with the following level compaction 0-0,2
k=3,9; for fine grain sand with the following level compaction 0,2-0,3 k=4,4; for
middle grain sand with the following level compaction 0,3-0,4 k=4,5;
q – an approximate expenditure of charge outburst,
kg/m

;
W – the line of least resistance,
m
;
h
cont
– the height of ground containment of trench charge outburst,
m
;
Q – mass of charge outburst,
kg
;
φ
– the corner of ground containment of trench charge outburst, degree.
2. The change of ground zone compaction of flowing ground mass on the
center of the charge outburst with the use of aluminum hydroxide solution de-
pending on angle of ground containment. It is calculated by the following formula:
,
m
(6)
for all types of grounds k=0,15.
3. The change of ground zone compaction of flowing ground mass on
the lower trimming of the charge outburst with the use of aluminum hydrox-
ide solution depending on angle of ground containment. It is calculated by
the following formula:
,
m
(7)
for all types of ground k=0,15.
