Subject: dragline and truck-shovel operations mining.
Please help to translate:

Waste dumps self heating management practices for dragline and truck-shovel operations follow.

Правильно ли я понимаю, что речь идет о
" ........ при формировании породных отвалов при помощи драглайнов и вагонеток"

Спасибо :)

Вагонеток там точно нет. Дайте больше контекста. Что там у вас follow?
Пока я поняла лишь, что речь идет о мерах по предотвращению самовозгорания отвалов и об использовании драглайнов, самосвалов и мехлопат (одноковшовые экскаваторы).

Ниже целый абзац. Начала нет, так как это начало главы.

Self heating management practices for dragline and truck-shovel operations follow. Truck dumping practices which can be effective in prevention of self heating include:
• Controlled placement of carbonaceous overburden and partings within inert “pockets”
• Limiting lift height to 15 m maximum
• Covering all final surfaces with a 5 m layer of inert material
• Compacting final surfaces, as well as intermediate surfaces wherever possible.
• Spreading out and track rolling carbonaceous material to prevent heat buildup and oxygen ingress
• Sealing hot spoil with a cover of clay is an effective technique to control heating. Long term seal integrity then becomes an important issue
• (measures that reduce the development of gully erosion such as drainage backs – is it similar to scalloping or not? IM , drop structures and prompt revegetation may be required.
