Tas-Yuryakh-Mirny-Udachny Gas Pipeline, also known as Tas-Yuryakh-Mirny-Aykhal-Udachny Gas Pipeline, (Russian: МГ "Таас-Юрях-Мирный-Айхал-Удачный") is an operating gas pipeline in Russia.

It consists of an operating pipeline from Tas-Yuryakh, Republic of Sakha, to Aykhal, Republic of Sakha (Таас-Юрях - Мирный - Айхал), and a proposed expansion from Aykhal, Republic of Sakha, to Udachny, Republic of Sakha, Russia (Айхал - Удачный).

Location

The existing pipeline (Tas-Yuryakh-Mirny-Aykhal) starts in Tas-Yuryakh, Respublic of Sakha and runs to Aykhal, Republic of Sakha, Russia (Таас-Юрях-Мирный-Айхал).

Background

In March 2020, design and survey work has started for the proposed expansion of the pipeline from Aykhal, Republic of Sakha, to Udachny, Republic of Sakha (газопровод-отвод "Айхал-Удачный"). The project will include construction of a gas distribution station, intracity gas networks to gas consumption facilities, gas boilers, gas heaters for heating the mine air of the Udachny underground mine; the heating networks of Udachny will also be renovated.

In September 2021, Glavgosexpertiza of Russia reviewed project documentation and results of engineering surveys and issued approval for the project to go ahead. The construction was ongoing in 2022-2023. The pipeline is expected to be commissioned by the beginning of the heating season in 2023.

In March 2024, the construction was still ongoing. As of July 2024, there have not been any further updates.
