Department: Exploration Technology and Technique Geology.

At present a great meaning is spared to teaching of students with the use of computer. The program will allow secure the efficient access of students and specialists relating to planning of drilling works, to software through the Internet tools.

Actuality of the executed work is that a stage of planning of the drilling of bore-holes, according [1], is one of four basic stages of production cycle of the boring drilling, but indisputably is the most responsible, as errors on this stage conduce to great losses. The creation of the automated system of planning will allow substantially to lower the risk of error on the stage of planning. On the given stage, the automated systems of planning are already created, but they have some drawbacks. The matter is that practically all similar systems are projected, conformably to terms of oil and gas-extracting industry. The systems for the geological survey industry exist, but they are not universal. And the most important thing today there is not any program allowing through the Internet tools to execute geological-technical projects of prospecting bore-holes.

This task will be broken-down on smaller tasks. The following tasks are assumed:

1. Initial data analysis. Basic data are:
          - geological cut of the designed bore;
          - hole;-setting of designed mining hole.

2. Choice of equipment. Coming from the set of equipment, and also basic data the choice of the
          recommended equipment for conducting of boring works is made. The choice is conducted on the basis
          of technical descriptions of equipment.

3. Choice of construction of bore- hole is the most main stage. Construction of bore-hole is a base for the
          further computations and planning of technology of conducting of works. The use of previous
          developments is possible [3].

4. Choice rock cutting tool. Choice of rock cutting tool is based on the biggest degree of approaching of its
          sphere of application (category on drilling, group on cracking, group on abrasive, range of diameters,
          type of the boring drilling) to the terms of the designed works.

5. Computation of regime parameters. According to the known and generally accepted method the
          computation of three regime parameters is conducted: axial loading, frequency of rotation, serve of
          washing.

As a result of planning the following set of documents will be got:

- geological-technical project of well-boring;

- text of project with the ground and necessary computations;

Now in the program basic 3 modules are realized:

1. Computation of the power expended on the boring drilling;

2. Computation of boring column on durability;

3. Hydraulic computation.

The program will be able to decide a greater quantity of tasks at further revision.
