Don't hurt yourselves laughing, but here is the only interesting snippet that I could find relating to the Sagem Sirus, it was replaced by an Electra 2000.
The text was in French and between myself and 'Babbling Fishes' I sorted this piece of garble from it, the red bits are my guesstimates;
SAGEM SIRUS TRANSLATION:
During the years 1970 and 1980, the breaking-down of the tender coal in layers of moinsd' (
Less than) one meter (Nord-Pas-de-Calais, Provence) takes place by planes (
ploughs) pulled by the moteursélectriques (
electric motor) ones or hydraulics of a power of about 180 kw and of which speed atteint (
attained)1,25 m/s to 1,5 m/s. For the higher thicknesses and harder coals, in particular en Lorraine, one uses a simple or double drum shearer. These coal cutters are adapted to lanature (
the nature) of the layer: coal cutter SAGEM DTF, equipped with an arm of 1,70 meter, intervientdans
([intervenes]cuts in) thick layers whereas coal cutter SAGEM SIRUS is designed for layers thinner, of one to two meters of power. All these coal cutters are généralementtélécommandées (
generally controlled) either by radio or by wire. With the years 1990, a new generation of material is essential. Electra 2000 estune (
is one) powerful coal cutter brought into service at the unit of exploitation of Houve in May 1992. Elopement (
it allows) to carry out spectacular productivity gains because of its speed, sacapacity (
its capability) of cutting and the suppression of the shootings of mine (
eliminates the need to use explosives to loosen coal), factors of idle periods dansl' demolition (
during breakdowns); from now on, the shootings of mine (
blasting) are limited to the stone drifts. The last have used standard Electra brought into service on June 24, 2002 at the Unit of Exploitation of Merlebach pourl' exploitation (
for the extraction) of the Dora vein.
Of an average opening of 4,10 m 276 meters delonguor,(
of length) this vein was originally to be exploited on 1.157 meters and to produce close de
(to)1,5 million ton but the operating deficit will encourage CDF to stop the tôtque (
early) exploitation envisaged, in October 2003.Les (
the) mining methods remain deeply influenced by the nature of the terrainet (
ground and) of the layer. Such effective technology in such basin will be inoperative in such other, oumême (
or even) in another seat of the same basin. Thus, in the edge seams and semi-steep seams, Lebo sage (
the casing?) in the face remains an operation where manual know-how is dominating. Starting from uneenquête meticulous (
a meticulous investigation) carried out in 1994 with the Vouters well, in Lorraine, Catherine Roth appraisement shown how much, in these quasi-vertical building sites, the casing mobilized dessavoir (
knowledge)-to make ancestral (
